PREFACE
Thank you for purchasing the ADSP-BF53x EZ-Extender 1, Analog
Devices (ADI) extension board to the EZ-KIT Lite™ evaluation system
for ADSP-BF53x 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
(DSP) characteristics towards delivering signal processing performance in
a microprocessor-like environment.
The ADSP-BF53x EZ-KIT Lite and EZ-Extender are designed to be used
in conjunction with the VisualDSP++™ development environment. Visu-
alDSP++ 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. The evaluation suite of VisualDSP++
software included with the EZ-KIT Lite is limited in program memory
size for use solely with the EZ-KIT Lite product.
To learn more about Analog Devices development software, go to
http://www.analog.com/processors/tools/.
Example programs are available to demonstrate the capabilities of the
ADSP-BF53x EZ-Extender board.
The extender features:
• OmniVision Camera Interface
DConnection to OmniVision OV6630AA Evaluation Board
D32-pin, right angle, 0.1 in. spacing, female socket
Purpose of This Manual
vi ADSP-BF53x EZ-Extender 1 Manual
• High-Speed Converter (HSC) Evaluation Board Interface
D40-pin, right angle, 0.1 in. spacing, female socket to con-
nect to Analog-to-Digital Converter (ADC) boards
D40-pin straight, 0.1 in. spacing header to connect to Digi-
tal-to-Analog Converter (DAC) boards
DSwitch for clock routing and direction selection
DRJ45 with Serial Peripheral Interconnect (SPI) to configure
converter registers
•LCDInterface
D32-pin, right angle FLZ-type connector to connect to LCD
boards
• SMT Footprint Area
D1206 and 805 footprints
DSOIC24 and SOIC20 footprints
Purpose of This Manual
The ADSP-BF53x EZ-Extender 1 Manual describes the operation and con-
figuration of the components on the board. A schematic and a bill of
materials are provided as a reference for future ADSP-BF53x Blackfin pro-
cessor board designs.
Intended Audience
This manual is a user’s guide and reference to the ADSP-BF53x
EZ-Extender 1. Programmers who are familiar with the Analog Devices
Blackfin processor architecture, operation, and development tools are the
primary audience for this manual.

Preface
Programmers who are unfamiliar with VisualDSP++ or EZ-KIT Lite eval-
uation software should refer to the ADSP-BF53x EZ-KIT Lite Evaluation
System Manual, VisualDSP++ online Help, and user’s or getting started
guides. For the locations of these documents, refer to “Product Related
Documents”.
Manual Contents
The manual consists of:
• Chapter 1, “Using EZ-Extender” on page 1-1
Provides basic board information.
• Chapter 2, “EZ-Extender Hardware Reference” on page 2-1
Provides information on the hardware aspects of the board.
• Appendix A, “Bill Of Materials” on page A-1
Provides a list of components used to manufacture the
EZ-Extender board.
• Appendix B, “Schematics” on page B-1
Provides the resources to allow EZ-Extender board-level debug-
ging or to use as a reference design.
This appendix is not part of the online Help. Go to the PDF ver-
sion of the ADSP-BF53x EZ-Extender 1 Manual located in the
Docs\EZ-KIT Lite Manuals folder on the VisualDSP++ installation
CD to see the schematics.
