PCI Express® Multiplexing
The TS2PCIE2212 can be used to multiplex/demultiplex two
PCI Express® lanes. The switch operates at the PCI Express
2.5-Gbps signal-processing speed and comprises two banks.
Each bank accommodates two sources (A and B) and two
destinations (A and B).
When a logic-level low is applied to the control pin (CTRL),
source A is connected to destination A and source B is connected to destination B. When a logic-level high is applied to
CTRL, source A is connected to destination B, while source B
and destination A are open.

Suggested Devices
As more features and processing requirements are added
to computing applications, the limited number of GPIOs on
micro­processors is becoming restricting. By implementing
I2C I/O expanders from TI, designers can use the GPIOs
for important functions and the I2C I/O expanders for duties
like temperature sensing and keypad communications.

The TS2PCIE412 and TS2PCIE2212 can be used to multiplex/demultiplex PCI Express lanes. Each switch has four
pairs and can be used in transmitting lanes or receiving lanes.
The example block diagram shows going to the MUX and
out to the DisplayPort and PCIe x 16 slots, since the MCH is
using a PCIe signal to operate the DisplayPort.
The select pin can be set low or high to choose the

Today, laptop computer USB ports are utilized not only for
data transmission but also as isolation for host charger
settings.
To enable laptop computers to charge portable equipment
in power-down mode or shut-down modes, it requires a USB
2.0 switch MUX to connect the circuit of the host charger,
which needs D+ and D– by 100-K resistor short. In iPod
charger mode it uses pull-up and pull-down resistors.
The CBT3125C is a quad SPST and can be applied to
both charging-mode connections.
The SN74CB3Q3253 is an alternative device for this
application, featuring dual SP4T with 500-MHz bandwidth
to meet USB 2.0 (480 Mbps with 240-MHz bandwidth
minimum).

HD Audio Bus Translator
V = 1.5 V
V = 3.3 V
Notebook
High Definition (HD) audio is quickly becoming the proven
method for audio signals, allowing for much higher quality play
back of audio signals compared to previously integrated audio
codecs. When the HD audio controller sends signals out to
either the audio codec or the modem codec, and voltage data
line discontinuity occurs, where one accepts 3.3 V and the
other 1.5 V. This is when our audio bus translators come in,
allowing for seamless voltage level translation between the
two mismatched voltages.
The HD_audio interface can be configured to use either
3.3 V or 1.5 V.
The TXB0106 is a 6-bit level translator that translates the
1.5-V interface to communicate with 3-V modem codec.
The total required HD_audio bus is 5 bits and may require
only 4 bits.

The major benefit of the TCA6408 device is its
wide VCC range. It can operate from 1.65-V to
5.5-V on the P port side and on the SDA/SCL
side. This allows the TCA6408 to interface with
next-generation microprocessors and microcontrollers on the SDA/SCL side, where supply
levels are dropping down to conserve power.
In contrast to the dropping power supplies of
microprocessors and microcontrollers, some
PCB components such as LEDs remain at a
5-V power supply.

ARM embedded processor operating voltages continue to
drop, depending on the process, level of integration and more
functions such as power saving.
Some processor I/Os need logic-level translators to
communicate between 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V
and 5-V nodes.
Netbook applications must support VGA video output.
Most 8-bit DAC logic interfaces are 3 V and need a 24-bit
level translator to communicate with processors that have
1.8-V or 2.6-V incompatible logic levels.
In the same way, SDIO is a 3-V standard push-pull/
open-drain I/F for memory cards that also needs 6-bit level
translators. The TXS0206 is a specific 6-bit translator that
integrates ESD, an EMI filter and pull-up/down resistors
to save space.

The TPS22949 is a 500-mW current-limit P-channel MOSFET
allowing input voltages from 1.62 V to 4.5 V and integrating
a 1.8-V low-noise LDO with separate enable pins. The OC
output flag indicates overcurrent, undervoltage or over
temperature.
A fingerprint module needs power isolation to protect the
sensor and prevent overcurrent damage.
The TPS22921 is an ultra-low ron 2-A non-current-limit load
switch with P-channel MOSFET. To accomodate the various
needs of slew rate and quick discharge, it has three options

TPS2294x load switches provide protection to systems
and loads in high-current conditions. The devices contain a
400-mW current-limited P-channel MOSFET that can operate
over an input voltage range of 1.62 V to 5.5 V. Current is
prevented from flowing when the MOSFET is off. The switch
is controlled by an on/off input (ON), which is capable of
interfacing directly with low-voltage control signals. The
TPS2294x includes thermal shutdown protection that
prevents damage to the device when a continuous overcurrent condition causes excessive heating by turning off
the switch.

TI low-dropout (LDO) linear regulators are low-quiescentcurrent devices with excellent line and load transient
performance. These LDOs are designed for power-sensitive
applications. A precision bandgap and error amplifier
provide up to 1 percent accuracy. Low output noise, a very
high power-supply rejection ratio (PSRR) and low dropout
voltage make this series of devices ideal for most batteryoperated handheld equipment. All device versions have
thermal shutdown and current limit for safety.

The PCA9555 consists of two 8-bit Configuration (input
or output selection), Input Port, Output Port, and Polarity
Inversion (active high or active low operation) registers. At
power on, the I/Os are configured as inputs. The system
master can enable the I/Os as either inputs or outputs by
writing to the I/O configuration bits. The data for each input
or output is kept in the corresponding Input or Output register.
The polarity of the Input Port register can be inverted with
the Polarity Inversion register. All registers can be read by
the system master.

multiple SFPs with the same I2C address are used, or there
can be multiple temperature sensors with the same I2C

An ESD strike is a constant threat to device reliability and
functionality. Many low-voltage core chips or system ASICs
offer only device-level human-body model (HBM) ESD protection, which does not address the risks of system-level
ESD strikes.
TI's stand-alone ESD solutions provide a space-saving
and cost-effective solution to protect system interconnects
from external ESD strikes. The TPD product family from TI
provides IEC 61000-4-2 level ESD protection, with solutions
for multiple external interfaces, including video, audio and
serial data transfer. TI's family of ESD devices meet requirements for low-power, small-footprint applications.

Often, there are not enough GPIOs available on the
microcontroller to control all of the desired peripherals. An
I2C bus expander can increase the number of GPIOs in the
system. The PCA9536 expands to four GPIOs while taking
up minimal board space with the 8-pin WCSP.

As operating voltage levels in microcontrollers continue to
drop, a void may be created between peripheral devices and
processors that disrupt interfacing between the devices. TI’s
translators enable communication between incompatible I/Os
with level translation between the 1.2-V, 1.5-V, 1.8-V, 2.5-V
and 3.3-V nodes.

ESD Protection
For any external interface connector port, an ESD strike is a
constant threat to device reliability. Many low-voltage core
chip or system ASICs offer only device-level human-bodymodel (HBM) ESD protection, which doesn’t address systemlevel ESD. A stand-alone ESD is a space- and cost-effective
solution to protect system interconnects from external ESD
strikes.
Advantages
• System-level ESD protection for high-speed applications:
• ±8-kV IEC 61000-4-2, contact discharge.
• ±15-kV IEC 61000-4-2, air-gap discharge.
• Less than 1.5 pF I/O pin capacitance.
• Ultra-low 1-nA leakage current.
• Operating supply voltage range: +0.9 V to +5.5 V.
• Space-saving packages: DRY, DRL, DRS and RSF.
Benefits
• System-level ESD protection for high-speed interconnects.
• Low capacitance suitable for USB 2.0 high-speed devices.
• Ultra-low 1-nA leakage current enables precision analog
measurements like a glucose meter.
• VCC pin allows devices to work as a transient suppressor.

Top Linear and Logic Device Requirements .
for Handsets
• Size
Board real estate is at a premium on PCBs. Small-scale
packaging is a requirement for linear and logic functions
on the design. From WCSP and micro-QFN packages
to industry-standard SC-70 and SOT-23 leadframe
packages, TI offers the industry’s broadest portfolio
of small-scale packaging.
• Power
Power consumption is critical in handset designs.
Consumers require long battery life with increased
functionality. TI’s AUP tech­nology requires 91 percent
less static power and 83 percent less dynamic power
than ­industry-standard 3.3-V logic.

One of the most common applications for analog switches is
signal routing. This may be routing from one source to multiple
destinations or from several sources to a single destination.
A single-pole, double-throw analog switch can be used for
either situation. For example, the switch could be used to
reroute the output of the audio power amplifier to two different
speakers. Another common application is switching from an
audio amplifier in the baseband of a mobile to an audio power
amplifier for higher power output.

Little Logic devices are needed on handsets to implement
simple logic functions, signal conditioning or bug fixing. With
TI’s configurable Little Logic devices, a single device can be
configured to perform as many as nine different logic functions. This reduces costs because only a single device, rather
than multiple logic parts, needs to be qualified, sourced and

Keypad control is one of the new application areas for I2C I/O
expanders. It is useful in end applications like PDA phones
that may need more than one keypad controller. For example,
some PDA phones include a software keypad and a hardware
keypad. In these cases, the processor can support one keypad and the second keypad can be controlled by an I2C I/O
expander like the TCA6408A. The TCA6408A can also be
used in portable medical devices where the microcontroller
is overloaded with several tasks. Here, the keypad function
can be transferred to the I2C I/O expander, which can then
support the few keys required in this application.

The TCA6507 is a 7-bit LED dimmer for a two-line bidirectional (I2C) bus designed to control (or dim) LEDs via the I2C interface (serial clock [SCL]/serial data [SDA]). Without this device,
the microprocessor or microcontroller must be actively involved
in turning on and off the LEDs (per the required dim­ming rate),
which uses valuable processor time and overloads the I2C bus.
The TCA6507 alleviates this issue by limiting the number of
operations the processor requires to blink the LEDs, thus
helping to create a more efficient system.

The LCD panel bus of a small LCD panel uses TTL/CMOS.
The logic level depends on the LCD driver and ranges from
2.7 V to 3.6 V.
The application processor I/F may be 2.6 V or lower and
need an external level shifter to shift the logic level to meet the
LCD panel bus.
TI offerings are available in 20 bits, 24 bits and 32 bits. The
32-bit SN74AVC32T245ZRL is the smallest package with
the lower cost structure.

As operating voltage levels in baseband
processors continue to drop, a void may
be created between peripheral devices and
processors that disrupts interfacing between
the devices. TI's translators enable communication between incompatible I/Os, with
level translation between the 1.2-V, 1.5-V,
1.8-V, 2.5-V, 3.3-V and 5-V nodes.

A SIM card bus power has 1.8 V, 3 V and 5 V supply
voltages; the logic I/F is based on the power supply range.
If it is going to support all types, it needs an external level
shifter. If it supports dual SIM cards, it could also need an
analog switch to select the desired cards.
IC-USB is a new bus that implements an internal
peripheral chip; and today, some SIM cards use IC-USB
to increase the size of flash memory.

Because electrostatic discharge (ESD) is
common in electronic circuits, a device that
provides protection from the undesirable
effects of ESD must be included in the
circuit design. Designing advanced ESD
protection structures is becoming more
and more challenging with the system bus
and I/O operating more often in high-speed
mode.

TPS2290x load switches are ultra-small, low ON
resistance (ron) load switches with controlled turn
on. The devices contain a P-channel MOSFET
that operates over an input voltage range of 1.0 V
to 3.6 V. The switch is controlled by an on/off
input (ON), which is capable of interfacing directly
with low-voltage control signals. In TPS22902
and switches TPS22902B and TPS22904, a
120-W on-chip load resistor is added for output
quick discharge when the switch is turned off.

TPS2294x load switches provide protection to systems
and loads in high-current conditions. The devices contain a
400-mW current-limited P-channel MOSFET that can operate
over an input voltage range of 1.62 V to 5.5 V. Current is
prevented from flowing when the MOSFET is off. The switch
is controlled by an on/off input (ON), which is capable of
interfacing directly with low-voltage control signals. The
TPS2294x includes thermal shutdown protection that
prevents damage to the device when a continuous overcurrent condition causes excessive heating by turning off
the switch.

• Robust Design
Higher ESD exposure and higher noise levels and temperatures make the industrial environment harsher and
less forgiving. TI offers a wide array of products with
enhanced system-level ESD protection and better noise
immunity. In addition, many of our standard products
offer an extended temperature range of up to 125°C.
• Reliable Supply
The typical lifetime for industrial applications is very long,
and TI has one of the best product obsolescence policies
in the market.

TI devices are designed for LED displays and LED lighting
applications with constant-current control and open-load,
shorted-load, and over-temperature detection. These LED
drivers provide great flexibility and device performance; they
need an 8-bit, 16-bit or 24-bit shift register and data latches,
which convert serial input data into a parallel output format.
At the output stage, regulated current ports are designed to
provide uniform and constant current for driving LEDs.

TI low-dropout (LDO) linear regulators are low-quiescentcurrent devices with excellent line and load transient
performance. These LDOs are designed for power-sensitive
applications. A precision bandgap and error amplifier
provide up to 1 percent accuracy. Low output noise, a very
high power-supply rejection ratio (PSRR) and low dropout
voltage make this series of devices ideal for most batteryoperated handheld equipment. All device versions have
thermal shutdown and current limit for safety.

I2C Control
As more features and processing requirements are added
to applications such as LED control and camera interfaces
in handsets, the limited number of GPIOs on microprocessors
is becoming restricting. By implementing I2C I/O expanders
from TI, designers can use the GPIOs for important functions
and the I/O expanders for other duties, like temperature
sensing and keypad communications.

For any external interface connector port, an ESD strike
is a constant threat to device reliability. Many low-voltage
core chip or system ASICs offer only device-level humanbody-model (HBM) ESD protection, which doesn’t address
system-level ESD. A stand-alone ESD solution is a spaceand cost-effective solution to protect system interconnects
from external ESD strikes.

TPS2290x load switches are ultra-small, low ON resistance
(ron) load switches with controlled turn on. The devices
contain a P-channel MOSFET that operates over an input
voltage range of 1.0 V to 3.6 V. The switch is controlled by
an on/off input (ON), which is capable of interfacing directly
with low-voltage control signals. In TPS22902 and switches
TPS22902B and TPS22904, a 120-W on-chip load resistor
is added for output quick discharge when the switch is
turned off.

TPS2294x load switches provide protection to systems
and loads in high-current conditions. The devices contain a
400-mW current-limited P-channel MOSFET that can operate
over an input voltage range of 1.62 V to 5.5 V. Current is
prevented from flowing when the MOSFET is off. The switch
is controlled by an on/off input (ON), which is capable of
interfacing directly with low-voltage control signals. The
TPS2294x includes thermal shutdown protection that
prevents damage to the device when a continuous overcurrent condition causes excessive heating by turning off
the switch.

Power consumption is critical in large telecom designs.
The more power an IC consumes, more the hardware
designers are concerned about heat dissipation and how
to cool the system to acceptable levels. Leading solutions
from TI offer the required low-power performance.

As operating voltage levels in microprocessors continue to
drop, a void may be created between peripheral devices
and processors that disrupts interfacing between them. TI’s
translators enable communication between incompatible I/Os,
with level translation between the 1.2-V, 1.5-V, 1.8-V, 2.5-V,
3.3-V and 5-V nodes.

Designers can make better use of their scarce GPIOs by using
TI’s I2C I/O expanders and multiplexers to time-share multiple
peripherals to a single I2C port. For example, I/O expanders
and multiplexers can be used to monitor and control a total
system by taking advantage of the already available
I2C bus.
Designers can also use I2C MUXes and switches to resolve
address conflicts on the I2C bus. In some server designs,
multiple SFPs with the same I2C address are used, or there
can be multiple temperature sensors with the same I2C
address. I2C MUXes and switches facilitate smooth operation
by selecting which device the master or processor should
communicate with at the appropriate time.

TI devices are designed for LED displays and LED lighting
applications with constant-current control and open-load,
shorted-load, and over-temperature detection. These LED
drivers provide great flexibility and device performance; they
need an 8-bit, 16-bit or 24-bit shift register and data latches,
which convert serial input data into a parallel output format.
At the output stage, regulated current ports are designed to
provide uniform and constant current for driving LEDs.

One of the most common applications for switches is routing
video signals. A typical television or other video system may
need the ability to switch between multiple sources to a
single receiver. This is a cost savings, as a single receiver
can essentially be expanded into two or more ports with a
relatively inexpensive video switch. Each video switch has a
specific application depending on its characteristics. The most
common applications are component video, composite video,
S-video and emerging HDMI. HDMI is a fully digital interface
that includes high-definition video and 5.1 audio.

One of the most common applications is to switch multiple
video input types to the video controller. Depending on the
video bandwidth difference, the right video switch has to be
selected correctly.
PC VGA video input and analog standard components
(HDTV) are common video inputs to LCD monitor display,
media
display and LCD TV. It needs a 3-bit high-bandwidth SPDT to
switch the desired input to a video controller.
HDVI, DVI and DisplayPort are standard digital video types
using the high data rate differential signal. They require highspeed FET switches.

One of the most common applications for analog switches is
signal routing. This may be routing from several sources to
various destinations. A single-pole, quadruple-throw analog
switch can be used in this situation. The switch can reroute
the output of multiple sources to a common audio processor.

As the video chipset becomes increasingly more complex,
more pins on a typical video controller are being used by new
features offered in that chipset. At the same time, reducing
the number of GPIOs that control external devices such as
video switches, receivers and other peripherals helps reduce
the video chipset’s cost. I2C I/O expanders allow for the
expansion of these GPIOs when more are needed.

For any external HDMI interface connector port, an ESD strike
is a constant threat to device reliability. Many low-voltage core
ICs offer only device-level human-body-model (HBM) ESD
protection, which doesn’t address system-level ESD. A standalone ESD is a space- and cost-effective solution to protect
system interconnects from external ESD strikes.

The I2C bus is used in a wide range of
applications because it is simple and
quick to use. It consists of a two wire
communication bus that supports
bidirectional data transfer between a
master and several slaves. The master
or processor controls the bus – in
particular, the serial clock (SCL) line.
Data is transferred between the master
and slave through a serial data (SDA) line.

Most LCD monitors use the external AC/DC adapter and a
+12-VDC input. The main requirements of DC power are 5 V,
3.3 V and 2.5 V.
TI offers commodity power devices managing different
voltage requirements of 9 V, 5 V, 3.3 V and 2.5 V.
The TLV1117 is designed to be stable with tantalum
and aluminum electrolytic output capacitors having an ESR
between 0.2 W and 10 W. Unlike pnp-type regulators, in
which up to 10 percent of the output current is wasted as
quiescent current, the quiescent current of the TLV1117
flows into the load, increasing efficiency.

HDMI and DVI interfaces are high-data-rate digital-differential
video inputs. They need a lower CIN ESD to reduce distortion
and improve system reliability.
HDMI has a 4-pair (8-bit) high-speed TMDS, 0.8-pF CIN
and 5-V level low-speed signals of DDC (SDA, SCL), HPD
and CEC. Because most HDMI receiver chips operate at
3.3 V it also needs a level shifter between the connector
and controller.
The TPD12S520 is an integrated 12-bit system ESD
protector that has a 4-bit optional level shifter for DDC,
HPD and CEC signals.
The TPD4S009/TPD4S010 and TPD8S009 are designed
for high-speed main link by 4-bits and 8-bits, with lower CIN
values.

ESD Protection
TI’s analog switches are designed to
pass (or isolate) analog signals (both
voltage and current) and support
analog applications such as audio and
video data transmission. TI analog
switches are available in a wide range
of voltages (from 0.8 V to 40 V),
support fast data throughput (up to
300-MHz bandwidth) and offer low
on-resistance and input capacitance
for decreased signal distortion and
insertion loss.

There are various types of set-top boxes: IP-set-top boxes,
HD-DVD, terrestrial set-top boxes, satellite set-top boxes,
HDTV boxes, VOD and digital set-top boxes.
USB, HDMI and 1394 are high-speed signal video bus
interfaces. They require lower con ESD to reduce distortion
during high-speed transmission.
The TPD4S009 and TPD4S010/TPD8S009 are high-speed
(up to 3 GHz with less than 1 pF) and meet USB, 1394, DVI,
HDMI and DisplayPort standards.
The TPD12S521 is an integrated HDMI/DVI ESD protector
with level shifting functionality as well as a 55-mA output
current limit.

Overview
Top Linear and Logic Device Requirements .
for White Goods
• Size
Board real estate is at a premium on PCBs. Small-scale
packaging is a requirement for linear and logic functions
on the design. From WCSP and micro-QFN packages
to industry-standard SC-70 and SOT-23 leadframe
packages, TI offers the industry’s broadest portfolio
of small-scale packaging.
• Relay Control
Most microcontrollers are not capable of withstanding
the large transients incurred during relay switching. The
TPL920x series of relay drivers integrates eight low-side
drivers, features power-on reset and an on-board 5-V
regulator, and is controlled with a serial interface that
simplifies system design and part count.

One of the most common applications for analog switches is
signal routing. This may be routing from one source to multiple
destinations or from several sources to a single destination. A
single-pole, double-throw analog switch can be used for either
situation. For example, the switch could be used to select different gain settings on an operational amplifier.

TI devices are designed for LED displays and LED lighting
applications with constant-current control and open-load,
shorted-load, and over-temperature detection. These LED
drivers provide great flexibility and device performance; they
need an 8-bit, 16-bit or 24-bit shift register and data latches,
which convert serial input data into a parallel output format.
At the output stage, regulated current ports are designed to
provide uniform and constant current for driving LEDs.

TI low-dropout (LDO) linear regulators are low-quiescentcurrent devices with excellent line and load transient
performance. These LDOs are designed for power-sensitive
applications. A precision bandgap and error amplifier
provide up to 1 percent accuracy. Low output noise, a very
high power-supply rejection ratio (PSRR) and low dropout
voltage make this series of devices ideal for most batteryoperated handheld equipment. All device versions have
thermal shutdown and current limit for safety.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
