1 EZ-EXTENDER INTERFACES
This chapter relates how the extender interfaces with the compatible
boards. The information is presented in the following sections.
• “ADC HSC Interface” on page 1-1
• “Breadboard Area” on page 1-2
ADC HSC Interface
The SHARC EZ-Extender can connect to an analog-to-digital high-speed
converter (ADC HSC) evaluation board via the ADC HSC interface. The
ADC HSC interface consists of a 40-pin female header, which contains all
of the control and data signals necessary to transfer data between the parallel data access port (PDAP) of the processor and the HSC evaluation
board. Additionally, the extender provides a RJ-45 connector, which contains all of the serial peripheral interconnect (SPI) signals necessary to
configure the control registers of capable high-speed converters. For a
block diagram of the ADC HSC interface, see Figure 2-1.
Before using the SHARC EZ-Extender, familiarize yourself with the documentation and schematics of the target board and the ADSP-21262
EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to
disable other devices on the PDAP or disable the push buttons.
To configure the SHARC EZ-Extender to connect to an ADC HSC evaluation board, determine the source of the PDAP clock and the direction
of the general-purpose signals, DAI_P15_GP1 and DAI_P16_GP2. To learn
about possible clock settings, refer to “Direction/Clock Source Control
SHARC EZ-Extender Manual
1-1
Breadboard Area
Switch (SW1)” on page 2-3. The setup of the general-purpose signals
DAI_P15_GP1 and DAI_P16_GP2 is dependent on the specific ADC HSC
evaluation board being interfaced; therefore, the board’s model must be
taken into consideration.
The data bus of the EZ-Extender must be enabled before data is read.
Enable the data bus by a memory read from address 0x160 0000, which
the AD[15:0] pins set up as the external port. Then, the AD[15:0] pins can
be set up in PDAP mode.
To learn more about Analog Devices data converters, go to
www.analog.com.
Breadboard Area
SHARC EZ-Extender broadens the range of the EZ-KIT Lite applications
by providing surface mounted (SMT) footprints for breadboard capabilities and access to all of the pins on the EZ-KIT Lite’s expansion interface.

2 EZ-EXTENDER HARDWARE
REFERENCE
This chapter describes the hardware design of the SHARC EZ-Extender.
The following topics are covered.
• “System Architecture” on page 2-1
Describes the configuration of the extender and explains how the
board components interface with the processor and EZ-KIT Lite.
• “DIP Switches and Jumpers” on page 2-3
Describes the function of the configuration DIP switches and
jumpers.
System Architecture
A detailed block diagram of the SHARC EZ-Extender is shown in
Figure 2-1. Note that the arrow in the bidirectional driver symbols
denotes the direction of the driver when in transmit mode. The bidirectional driver is in transmit mode when the direction pin is pulled high.
Use the diagram in conjunction with information in “DIP Switches and
Jumpers” on page 2-3 section of this manual to configure your SHARC
EZ-Extender.
Before using the SHARC EZ-Extender, familiarize yourself with the documentation and schematics of the target board and the ADSP-21262
EZ-KIT Lite. For example, on the EZ-KIT Lite, it may be necessary to
disable other devices on the parallel data access port (PDAP) or disable the
push buttons.

System Architecture
Figure 2-1. SHARC EZ-Extender Block Diagram
The block diagram in Figure 2-1 shows that each clock and general-purpose signal attached to the analog-to-digital high-speed converter (ADC
HSC) interface is configured depending on how the interface operates.
The EZ-Extender has two clock signals, TX_CLK and RX_CLK. The TX_CLK
signal is used as an output and can be generated in three ways: by applying
a signal via an SMA connector, by using the RX_CLK signal, or by
2-2

EZ-Extender Hardware Reference
populating a socket with an oscillator. Only one of these sources can be
used at a time, the other sources must be disabled. For more information
on how to disable the TX_CLK sources, see “SMA Connector Clock Disconnect Jumper (P10)” on page 2-5. The RX_CLK signal is generated by the
target board. Both the TX_CLK and RX_CLK can connect to the processor’s
clock-in signal (DAI_P2_CLOCKIN) as an input. See “Direction/Clock
Source Control Switch (SW1)” on page 2-3 for more information.
The ADC interface has two general-purpose signals, DAI_P15_GP1 and
DAI_P16_GP2. The evaluation board with which the extender interfaces
determines how these signals are set up. For information on how to set the
direction and the source of these signals, refer to “Direction/Clock Source
Control Switch (SW1)” on page 2-3.
The ADC interface connects to the PDAP of the ADSP-21262 processor.
The PDAP is multiplexed with the address and data bus. To avoid bus
contention with the memory devices on the EZ-KIT Lite, the driver connected to the data bus of the ADC must be enabled. For more information
about enabling the data bus, see “ADC HSC Interface” on page 1-1.
DIP Switches and Jumpers
The following section describes the function of all of the jumpers and
switches on the EZ-Extender. Before connecting the extender, familiarize
yourself with each possible setting’s effect on your application.
Direction/Clock Source Control Switch (SW1)
A designated DIP switch, SW1, provides an independent direction control
for the general-purpose signals (DAI_P15_GP1 and DAI_P16_GP2), as illustrated in Figure 2-1. Each signal can be hardwired to be either transmit or
receive, or can be changed in real time using the DAI_P18 processor pin. If
the DAI_P18 processor pin is intended for the direction control, ensure the
pin is not used for other purposes on the EZ-KIT Lite. When the SW1

switch connects a direction control signal to ground (GND), the corresponding signal (signals) is (are) controlled as input. The direction control
functionality is summarized in Table 2-1.

MISO Disconnect Jumper (P6)
The MISO signal of the serial peripheral interconnect (SPI) connector (J2)
is driven by a buffer to the processor’s MISO signal, as illustrated in
Figure 2-1. When the SPI connector is not in use, remove the P6 jumper
to prevent the signal from interfering with other devices on the SPI bus.
SMA Connector Clock Disconnect Jumper (P10)
The SMA connector (J3) enables a clock input from a signal generator or
from other clock source. The input signal is directed though a buffer, as
illustrated in Figure 2-1. When the SMA connector is not in use, remove
the P10 jumper to prevent the buffer from driving other signals on the net.
