Regulatory Compliance
The Blackfin A-V EZ-Extender has been certified to comply with the
essential requirements of the European EMC directive 89/336/EEC
(inclusive 93/68/EEC) and, therefore, carries the “CE” mark.
The Blackfin A-V EZ-Extender had been appended to Analog Devices
Development Tools Technical Construction File referenced
“DSPTOOLS1” dated December 21, 1997 and was awarded CE Certifi-
cation by an appointed European Competent Body and is on file.
The EZ-KIT Lite evaluation system contains ESD
(electrostatic discharge) sensitive devices. Electro-
static 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.

Blackfin A-V EZ-Extender Manual ix
PREFACE
Thank you for purchasing the Blackfin®A-V EZ-Extender®, Analog
Devices, Inc. (ADI) extension board to the EZ-KIT Lite®evaluation sys-
tem 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 A-V EZ-Extender are designed to be used in con-
junction 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 proces-
sor, reducing time-to-market.
To learn more about Analog Devices development software, go to
http://www.analog.com/processors/tools/.
Product Overview
The Blackfin A-V 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 ADSP-BF533, ADSP-BF537, or
ADSP-BF561 processor targeted applications.

INTERFACES
This chapter provides a setup procedure for the Blackfin A-V
EZ-Extender, an EZ-KIT Lite (ADSP-BF533, ADSP-BF537 or
ADSP-BF561), and an evaluation module. The chapter also describes each
of the evaluation interfaces the extender supports.
The information is presented in the following order.
•“A-V EZ-Extender Setup” on page 1-1
•“Analog Audio Interface” on page 1-2
•“Analog Video Interface” on page 1-3
•“Camera Module Interfaces” on page 1-4
•“Flat Panel Display Interface” on page 1-6
A-V EZ-Extender Setup
It is very important to set up all of the components of the system contain-
ing the A-V EZ-Extender before applying power to that system.
Power your system when these steps are completed:
1. Read the applicable design interface section in this chapter—the
text provides an overview of the capabilities of the interface.
2. Read “System Architecture” on page 2-2 to understand the physical
connections of the extension board. For detailed information, refer
to “A-V EZ-Extender Schematic” on page B-1.
www.BDTIC.com/ADI

Analog Audio Interface
1-2 Blackfin A-V EZ-Extender Manual
3. Set the jumpers on the A-V EZ-Extender board. Use the block dia-
gram in Figure 2-1 on page 2-3 in conjunction with “Jumpers” on
page 2-7.
4. Set the switches and jumpers on the EZ-KIT Lite board. If not
already, familiarize yourself with the documentation and schemat-
ics of the EZ-KIT Lite (see “Related Documents”). Compare the
expansion interface signals of the A-V EZ-Extender board with the
signals of the EZ-KIT Lite board to ensure there is no contention.
For example, it may be necessary to disable other devices connected
to the parallel peripheral interface (PPI) of the processor, change
the routing of the PPI clocks and disable the push buttons.
5. Configure any other interfacing boards, for example, another
EZ-Extender or camera evaluation board.
Analog Audio Interface
For an audio application, the Blackfin A-V EZ-Extender uses the
AD1836A multichannel 96 kHz audio codec. The AD1836A is a
high-performance single-chip codec that provides three stereo digi-
tal-to-analog converters (outputs) and two stereo analog-to-digital
converters (inputs) using ADI’s patented multi-bit sigma-delta architec-
ture. The board includes a serial peripheral interface (SPI) port, allowing
the processor to adjust volume and other parameters. For a general over-
view of the audio interface connections, see Figure 2-1 on page 2-3. For
more detailed information, see “A-V EZ-Extender Schematic” on
page B-1.
SPORT0 of the expansion interface interfaces with the serial port of the
AD1836A codec. The processor is capable of transferring data to the
audio codec in time-division multiplexed (TDM) or I2S mode. The I2S
mode allows the codec to operate at a 96 kHz sample rate but allows only
two channels of output. TDM mode can operate at a maximum of 48 kHz
