Regulatory Compliance

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

Development Tools Technical Construction File referenced

“DSPTOOLS1” dated December 21, 1997 and was awarded CE Certifi-

cation by an appointed European Competent Body and is on file.

The EZ-KIT Lite evaluation system contains ESD

(electrostatic discharge) sensitive devices. Electro-

static 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

EZ-KIT Lite boards in the protective shipping

package.

PREFACE

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

Devices, Inc. (ADI) extension board to the EZ-KIT Lite®evaluation sys-

tem for ADSP-BF533, ADSP-BF537, and ADSP-BF561 Blackfin

processors.

The 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.

The EZ-KIT Lite and A-V EZ-Extender are designed to be used in con-

junction with the VisualDSP++®development environment.

VisualDSP++ offers a powerful programming tool with new flexibility that

significantly decreases the time required to port software code to a proces-

sor, reducing time-to-market.

Product Overview

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

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

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

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

ADSP-BF561 processor targeted applications.
