Regulatory Compliance
The Audio EI3 Extender Board is designed to be used solely in a laboratory environment. The board is not intended for use as a consumer end
product or as a portion of a consumer end product. The board is an open
system design which does not include a shielded enclosure and therefore
may cause interference to other electrical devices in close proximity. This
board should not be used in or near any medical equipment or RF devices.
The Audio EI3 Extender Board is in the process of being certified to comply with the essential requirements of the European EMC directive
89/336/EEC (inclusive 93/68/EEC) and, therefore, carries the “CE”
mark.
The extender board contains ESD (electrostatic discharge) sensitive devices.
Electrostatic charges readily accumulate on the human body and equipment
and can discharge without detection. Permanent damage may occur on
devices subjected to high-energy discharges. Proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
Store unused extender boards in the protective shipping package.

PREFACE
Thank you for purchasing the Audio EI3 Extender Board, an
EZ-Extender® product for EZ-KIT Lite®/EZ-Board® evaluation systems.
The EZ-KIT Lite/EZ-Board and Audio EI3 Extender Board are designed
to be used in conjunction with the CrossCore® Embedded Studio development environment. CrossCore Embedded Studio (CCES) offers a
powerful programming tool with new flexibility that significantly
decreases the time required to port software code to a processor, reducing
time-to-market.
To learn more about Analog Devices development software, go to
http://www.analog.com/processors/tools.
Product Overview
The Audio EI3 Extender Board is a separately sold daughter board that
plugs onto the expansion interface (EI3) of an EZ-KIT Lite/EZ-Board
evaluation system. The extender board aids the design and prototyping
phases of the embedded processor-targeted applications. For more information refer to the product website, http://www.analog.com/EI3-Audio.
The Audio EI3 Extender Board utilizes the ADAU1761 SigmaDSP®
stereo, low power, 96 kHz, 24-bit audio codec. The codec provides line
input, line output, auxiliary input and headphone output.

Audio EI3 Extender Board Manual
Using Audio EI3 Extender Board
System Requirements
Verify that your PC has these minimum requirements for the CCSE
installation:
• 2 GHz single-core processor
• 1 GB RAM
• 8 GB available disk space
• One open USB port
A faster disk drive decreases the build time, especially for a large
 amount
of source files.
Audio EI3 Extender Board Setup
The Audio EI3 Extender Board does not have any configuration that is
required. Make sure the EZ-KIT Lite/EZ-Board that the Audio EI3
Extender Board will be connected to is set up properly.
Before powering the board, use the provided hardware to secure the
extender to the EZ-KIT Lite/EZ-Board. The small spacers are intended
for between the extender board and the mating board. If used, standoffs
on the EZ-KIT Lite/EZ-Board may need to be removed. The extender
board uses shorter standoffs and a screw secures these standoffs.
Refer to the readme text files in the CrossCore Embedded Studio directory (<install_path>\Audio_EI3_Extender_Board-RelX.X.X\Audio_EI3,
where X.X.X denotes the support package release number) for information
on how to configure the EZ-KIT Lite boards. For more information on
the Audio EI3 Extender Board, please go to http://www.analog.com/
EI3-Audio. The board support package (BSP) for the Audio EI3 Extender
Board can be found at this website.

Audio Interface
Audio Interface
The SigmaDSP ADAU1761 (U2) connects to the SPORT interface of the
EI3 connector (J1). All control and setup communication uses the TWI
interface. The TWI address is set to 0111 000X (where X is the read or
write bit) by resistors R9 and R10. The last two address bits can be
adjusted through populating R7 and/or R8, in conjunction with depopulating R9 and/or R10.
There are two input connectors and two output connectors. J2 is the stereo headphone output. J3 is line out and is a single-ended stereo output.
J5 is the auxiliary input. J4 connects a single-ended stereo line in to the
codec. A standard 3.5 mm male-to-male cable connects to any of these
four connectors.
The board also has two omnidirectional MEMS microphones, which are
Analog Devices part number ADMP421 ICs (U3 and U4). The microphones connect gluelessly to the ADAU1761 processor.
Example programs demonstrating the audio interface capabilities are
included in the CrossCore Embedded Studio directory. Once installed,
the example programs can be found in the <install_path>\Audio_EI3_
Extender_Board-RelX.X.X\Audio_EI3 directory, where X.X.X denotes the
support package release number.
Connectors
The LED, connector, and jumper locations are shown in Figure 1-1.
The J2–J5 connectors are 3.5 mm stereo jacks from CUI Inc. (part number SJ-3523-SMT). Use any 3.5 mm audio cable to connect to J2–J5.
The P1 connector is a 0.65 mm power jack from CUI Inc. (part number
CP1-022PJTR-ND). Use this jack when the EZ-KIT Lite/EZ-Board cannot provide adequate power. The 5V adaptor is then connected to P1 and
1-4
Audio EI3 Extender Board Manual
Using Audio EI3 Extender Board
the main board produces the 1.8–3.3V needed for the Audio EI3 Extender
Board to operate on the signal VIO.
The J1 connector is a 120-pin 0.6 mm pitch connector from Hirose (part
number FX8-120S-SV(21)). This connector mates with Hirose part number FX8-120P-SV1(91).
P2 is the SigmaStudio interface connector. The interface cable is Analog
Devices part number EVAL-ADUSB2EBZ, which is available through
www.analog.com. This provides a USB connection to a host PC and the
full capabilities of the SigmaDSP ADAU1761 are available through SigmaStudio. Only the I2C interface of the connection is available.

Power LED (LED1)
Power LED (LED1)
The power LED (LED1) is located on the bottom of the board and is green
when the Audio EI3 Extender Board is powered.
Power
The Audio EI3 Audio Extender Board needs the EZ-KIT Lite/EZ-Board
to be powered and does not require power input to the P2 power
connector.
The VIO power rail of the Audio EI3 Extender Board must be in the range
of 1.8V–3.3V for proper operation. Ensure that any main board connected to the Audio EI3 Extender Board supplies this voltage over pin 116
of J1.
