Regulatory Compliance
The Blackfin/SHARC USB 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 there-
fore 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/SHARC USB EZ-Extender is currently being processed for
certification that it complies with the essential requirements of the Euro-
pean EMC directive 89/336/EEC amended by 93/68/EEC and therefore
carries the “CE” mark.
The Blackfin/SHARC USB EZ-Extender board contains ESD (electrostatic
discharge) sensitive devices. Electrostatic charges readily accumulate on the
human body and equipment and can discharge without detection. Perma-
nent damage may occur on devices subjected to high-energy discharges.
Proper ESD precautions are recommended to avoid performance degrada-
tion or loss of functionality. Store unused extender boards in the protective
shipping package.

PREFACE
Thank you for purchasing the Blackfin/SHARC USB EZ-Extender®,
Analog Devices, Inc. extender board to the EZ-Board®evaluation system
for the ADSP-BF518F, ADSP-BF526 Blackfin®, and ADSP-21469
SHARC®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.
SHARC processors are based on a 32-bit super Harvard architecture that
includes a unique memory architecture comprised of two large on-chip,
dual-ported SRAM blocks coupled with a sophisticated IO processor,
which gives a SHARC processor the bandwidth for sustained high-speed
computations. SHARC processors represents today’s de facto standard for
floating-point processing, targeted toward premium audio applications.
The EZ-Board and Blackfin/SHARC USB EZ-Extender are designed to
be used in conjunction with the CrossCore®Embedded Studio (CCES)
and VisualDSP++®software development environments. The develop-
ment environment facilitates advanced application code development and
debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and Blackfin/SHARC USB EZ-Extender assembly
• Load, run, step, halt, and set breakpoints in application programs

Product Overview
The Blackfin/SHARC USB EZ-Extender is a separately sold extender
board that plugs onto the expansion interface of the ADSP-BF518F,
ADSP-BF526, and ADSP-21469 EZ-Board evaluation systems. The
extender board aids the design and prototyping phases of the
ADSP-BF518F, ADSP-BF526, and ADSP-21469 processor targeted
applications.
The board extends the capabilities of the evaluation system by providing a
connection between the asynchronous memory bus of the Black-
fin/SHARC processor and a USB 2.0 device.
Please visit www.analog.com/EX2-USB for additional information, includ-
ing CCES support.
The following is a list of the Blackfin/SHARC USB EZ-Extender
interfaces.
• USB 2.0 interface:
• PLX Technology NET2272 device
• USB driver and application code
• No power supply required: derives power from the EZ-Board
• CE certified

Preface
Before using any of the interfaces, follow the setup procedure in “Black-
fin/SHARC USB EZ-Extender Setup” on page 1-1.
Example programs are available to demonstrate capabilities of the Black-
fin/SHARC USB EZ-Extender board.
Purpose of This Manual
The Blackfin/SHARC USB EZ-Extender Manual provides instructions for
installing the product hardware (board). The text describes operation and
configuration of the board components. Finally, a schematic and a bill of
materials are provided as a reference for future designs.
Intended Audience
The primary audience for this manual is a programmer who is familiar
with Analog Devices processors. This manual assumes that the audience
has a working knowledge of the appropriate processor architecture and
instruction set.
Programmers who are unfamiliar with Analog Devices processors can use
this manual but should supplement it with other texts that describe your
target architecture. For the locations of these documents, see “Related
Documents”.
Programmers who are unfamiliar with CCES or VisualDSP++ should refer
to the online help and user’s manuals.
