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
therefore may cause interference to other electrical devices in close prox-
imity. 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.
This 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 precau-
tions are recommended to avoid performance degradation or loss of func-
tionality. Store unused boards in the protective shipping package.

Blackfin/SHARC USB EZ-Extender Manual vii
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 VisualDSP++®development environ-
ment. 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
viii Blackfin/SHARC USB EZ-Extender Manual
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.
The following is a list of the Blackfin/SHARC USB EZ-Extender
interfaces.
• USB 2.0 interface:
DPLX Technology NET2272 device
DUSB driver and application code
• No power supply required: derives power from the EZ-Board
• CE certified
Before using any of the interfaces, follow the setup procedure in “Black-
fin/SHARC USB EZ-Extender Setup” on page 1-2.
Example programs are available to demonstrate capabilities of the Black-
fin/SHARC USB EZ-Extender board.

Blackfin/SHARC USB EZ-Extender Manual ix
Preface
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
(such as the Hardware Reference and Instruction Set Reference) that describe
your target architecture.
Programmers who are unfamiliar with VisualDSP++ or EZ-Board evalua-
tion software should refer to the ADSP-BF518F, ADSP-BF526, or
ADSP-21469 EZ-Board Evaluation System Manual, VisualDSP++ online
Help, and user’s or getting started guides. For locations of these docu-
ments, refer to “Product Information”.
