Regulatory Compliance The Audio EI3 Extender Board is designed to be used solely in a labora-tory 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 com-ply 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 devel-opment 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 OverviewThe 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 infor-mation 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.

1-2 Audio EI3 Extender Board Manual

Using Audio EI3 Extender Board

System RequirementsVerify 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 SetupThe 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 direc-tory (<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 EI3 Extender Board Manual 1-3

Audio Interface

Audio InterfaceThe 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 depopu-lating R9 and/or R10.

There are two input connectors and two output connectors. J2 is the ste-reo 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 micro-phones 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.

ConnectorsThe 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 num-ber 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 can-not 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 num-ber 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 Sig-maStudio. Only the I2C interface of the connection is available.

As shown in Figure 1-1, connector J1 is located on the opposite side of the board. For this reason, J1 is shown with a dashed line.

Audio EI3 Extender Board Manual 1-5

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.

PowerThe 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 con-nected to the Audio EI3 Extender Board supplies this voltage over pin 116 of J1.
