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 SHARC® EZ-Extender®, Analog Devices
(ADI) extension board to the EZ-KIT Lite® evaluation system for
ADSP-21262 SHARC processors.
The 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 SHARC the bandwidth for sustained high-speed
computations. SHARC represents today’s de facto standard for floating-point processors targeted for premium audio applications.
The SHARC EZ-Extender is designed to be used in conjunction with the
ADSP-21262 EZ-KIT Lite evaluation system. The EZ-KIT Lite includes
an evaluation suite of VisualDSP++® software, which is limited in program memory size for use solely with the EZ-KIT Lite product.
VisualDSP++ is a powerful programming tool with flexibility that significantly decreases the time required to port software code to a processor,
reducing time-to-market.
To learn more about Analog Devices development software, go to
http://www.analog.com/dsp/tools/.
Example programs are available to demonstrate the capabilities of the
SHARC EZ-Extender board.
The SHARC EZ-Extender is a separately sold assembly that plugs onto
the expansion interface of the ADSP-21262 EZ-KIT Lite evaluation
system.
SHARC EZ-Extender Manual vii
Purpose of This Manual
The board extends the capabilities of the evaluation system by providing a
connection between the parallel data access port (PDAP) of the
ADSP-21262 processor and an Analog Devices analog-to-digital
high-speed converter (ADC HSC) evaluation board. Moreover, the
extender broadens the range of the EZ-KIT Lite applications by providing
surface-mounted (SMT) footprints for breadboard capabilities and access
to all of the pins on the EZ-KIT Lite’s expansion interface.
The extender features:
• High-speed converter evaluation board interface
D 40-pin, right angle, 0.1 in. spacing, female socket to con-
nect to analog-to-digital converter boards
D Switches for routing and direction selection
D RJ-45 with serial peripheral interconnect (SPI) to configure
converter registers
• SMT footprint area
D 1206 and 805 footprints
D SOIC24 and SOIC20 footprints
• Dimensions
D 5 in (H) x 5 in (W)
Purpose of This Manual
The SHARC EZ-Extender Manual describes the operation and configuration of the components on the board. A schematic and a bill of materials
are provided as a reference for future ADSP-21262 processor board
designs.
