Regulatory Compliance

The Blackfin A-V EZ-Extender 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 Blackfin A-V EZ-Extender has been certified to comply with the

essential requirements of the European EMC directive 2004/108/EC and

therefore carries the “CE” mark.

The Blackfin A-V EZ-Extender has been appended to Analog Devices,

Inc. EMC Technical File (EMC TF) referenced DSPTOOLS1, issue 2

dated June 4, 2008 and was declared CE compliant by an appointed Noti-

fied Body (No.0673) as listed below.

The Blackfin A-V EZ-Extender contains ESD (electrostatic discharge) sen-

sitive 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 pre-

cautions are recommended to avoid performance degradation or loss of

functionality. Store unused extender boards in the protective shipping pack-

age.

PREFACE

Thank you for purchasing the Blackfin®A-V EZ-Extender®, Analog

Devices, Inc. daughter board to the EZ-KIT Lite®evaluation system for

the ADSP-BF533, ADSP-BF537, and ADSP-BF561 Blackfin processors.

Blackfin processors are embedded processors that support a Media

Instruction Set Computing (MISC) architecture. This architecture is the

natural merging of RISC, media functions, and digital signal processing

characteristics towards delivering signal processing performance in

a microprocessor-like environment.

EZ-KIT Lites and A-V EZ-Extenders are designed to be used in conjunc-

tion with the CrossCore®Embedded Studio (CCES) and VisualDSP++®

software development environments. The development environment facil-

itates advanced application code development and debug, such as:

• Create, compile, assemble, and link application programs written

in C++, C, and A-V EZ-Extender assembly

• Load, run, step, halt, and set breakpoints in application programs

• Read and write data and program memory

• Read and write core and peripheral registers

• Plot memory

Product Overview

x Blackfin A-V EZ-Extender Manual

Product Overview

The Blackfin A-V EZ-Extender is a separately sold daughter board that

plugs onto the expansion interface of the ADSP-BF533, ADSP-BF537, or

ADSP-BF561 EZ-KIT Lite evaluation system. The extender board aids

the design and prototyping phases of the ADSP-BF533, ADSP-BF537, or

ADSP-BF561 processor targeted applications.

The board extends the evaluation system capabilities by providing a con-

nection to a video decoder; video encoder; multiple camera evaluation

boards; flat panel display; and 3-stereo input channel, 2-stereo output

channel audio codec.

Please visit www.analog.com/EX1-AV for additional information, including

CCES support.

The board features:

• Analog audio interface

• AD1836A Analog Devices 96 kHz audio codec

• Five 3.5 mm audio jacks, stacked in one connector

• Analog video interface

• ADV7183B video decoder with three input RCA phono

jacks

• ADV7179 video encoder with three output RCA phono

jacks

• OmniVision camera module interface

• Connection to OmniVision camera evaluation modules;

for example, OV6630AA (this part is no longer available)

• 32-pin, right-angle, 0.1 in. spacing, female socket
