Regulatory Compliance
The USB-LAN EZ-Extender 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 USB-LAN EZ-Extender has been certified to comply with the essential requirements of the European EMC directive 89/336/EEC amended
by 93/68/EEC and therefore carries the “CE” mark.
The USB-LAN EZ-Extender has been appended to Analog Devices, Inc.
Technical Construction File (TCF) referenced ‘DSPTOOLS1’ dated
December 21, 1997 and was awarded CE Certification by an appointed
European Competent Body as listed below.

The EZ-KIT Lite evaluation system 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 EZ-KIT Lite boards in the protective
shipping package.

PREFACE
Thank you for purchasing the Blackfin® USB-LAN EZ-Extender®, Analog Devices, Inc. extension board to the EZ-KIT Lite® evaluation system
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 USB-LAN EZ-Extender are designed to be used in
conjunction 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 processor, reducing time-to-market.

Product Overview
Product Overview
The Blackfin USB-LAN 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 the
ADSP-BF533, ADSP-BF537, or ADSP-BF561 processor targeted
applications.
The board extends the capabilities of the evaluation system by providing a
connection between the asynchronous memory bus of the Blackfin processor (asynchronous memory bank 3) and either a USB 2.0 or a 10/100
Mbps Ethernet device.
The following is a list of the Blackfin USB-LAN EZ-Extender interfaces.
