Regulatory Compliance
The Blackfin A-V EZ-Extender is designed to be used solely in a labora-
tory 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 proximity. This
board should not be used in or near any medical equipment or RF devices.
The Blackfin A-V EZ-Extender has been certified to comply with the
essential requirements of the European EMC directive 2004/108/EC and
therefore carries the “CE” mark.
The Blackfin A-V EZ-Extender has been appended to Analog Devices,
Inc. EMC Technical File (EMC TF) referenced DSPTOOLS1, issue 2
dated June 4, 2008 and was declared CE compliant by an appointed Noti-
fied Body (No.0673) as listed below.

The Blackfin A-V EZ-Extender contains ESD (electrostatic discharge) sen-
sitive 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 pre-
cautions are recommended to avoid performance degradation or loss of
functionality. Store unused extender boards in the protective shipping pack-
age.

PREFACE
Thank you for purchasing the Blackfin®A-V EZ-Extender®, Analog
Devices, Inc. daughter board to the EZ-KIT Lite®evaluation system for
the ADSP-BF533, ADSP-BF537, and ADSP-BF561 Blackfin 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.
EZ-KIT Lites and A-V EZ-Extenders are designed to be used in conjunc-
tion with the CrossCore®Embedded Studio (CCES) and VisualDSP++®
software development environments. The development environment facil-
itates advanced application code development and debug, such as:
• Create, compile, assemble, and link application programs written
in C++, C, and A-V EZ-Extender assembly
• Load, run, step, halt, and set breakpoints in application programs
• Read and write data and program memory
• Read and write core and peripheral registers
• Plot memory

A-V EZ-Extender Setup
1-2 Blackfin A-V EZ-Extender Manual
A-V EZ-Extender Setup
It is very important to set up all components of the system containing the
Blackfin A-V EZ-Extender, then apply power to the system.
Power your system after these steps are completed:
1. Read the applicable design interface section in this chapter—the
text provides an overview of the interface capabilities.
2. Read “System Architecture” on page 2-2 to understand the physical
connections of the extender board. For more detailed information,
refer to “A-V EZ-Extender Schematic” on page B-1.
3. Set the jumpers on the extender board. Use the block diagram 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 schematic
drawing of the EZ-KIT Lite (see “Related Documents”). Compare
the expansion interface signals of the extender with the EZ-KIT
Lite signals 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 a camera evaluation board.

A-V EZ-Extender Interfaces
Analog Audio Interface
The Blackfin A-V EZ-Extender supports audio applications with the
on-board AD1836A multichannel 96 kHz audio codec. The AD1836A
codec is a high-performance single-chip device that provides three stereo
digital-to-analog converters (outputs) and two stereo analog-to-digital
converters (inputs), using Analog Devices patented multibit sigma-delta
architecture. The board includes a serial peripheral interface (SPI) port,
enabling the processor to adjust volume and other parameters. For a gen-
eral overview of the audio interface connections, see Figure 2-1 on
page 2-3; for details, see “A-V EZ-Extender Schematic” on page B-1.
SPORT0 of the expansion interface connects to the serial port of the
AD1836A codec. The processor is capable of transferring data to the
audio codec in time-division multiplexed (TDM) mode or I2S mode. In
I2S mode, the codec can operate at a 96 kHz sample rate and allows two
channels of output. In TDM mode, the codec can operate at a maximum
of 48 kHz sample rate and allows simultaneous use of all input and output
channels. To operate in I2S mode, install the JP7.1/2 jumper. For more
information, see “I2S Enable Jumper (JP7.1/2)” on page 2-13.
Internal registers of the AD1836A audio codec can be programmed via the
SPI port of the processor. (For information on how to program the config-
uration registers, refer to the AD1836A data sheet.) The AD1836A codec
reset comes from a flag pin located at PPI1_D11 of the expansion interface
or from the reset signal on the EZ-KIT Lite. For information on how to
configure the reset, see “AV_RESET Source Jumper (JP9.1/3/5)” on
page 2-14.
Before using the interface, follow the procedure in “A-V EZ-Extender
Setup” on page 1-2.
For more information about the codec, go to www.analog.com/AD1836A.

Analog Video Interface
1-4 Blackfin A-V EZ-Extender Manual
Analog Video Interface
The Blackfin A-V EZ-Extender supports video input and output applica-
tions with an on-board video encoder and decoder. The ADV7179 video
encoder provides up to three output channels of analog video, while the
ADV7183B video decoder provides up to three input channels of analog
video. Both the encoder and decoder connect to PPI0 of the expansion
interface, while the encoder also can connect to PPI1 (if the processor has
two PPI ports). For a general overview of the analog video interface con-
nectors, see Figure 2-1 on page 2-3; for details, see “AV_RESET Source
Jumper (JP9.1/3/5)” on page 2-14.
To use ADV7179 and ADV7183B, set up all of the jumpers related to the
PPI data signals, frame sync signals, and clock signal. To program the
internal register of video devices, configure the 2-wire interface signals (see
“TWI Source Selection Jumpers (JP3.3/5/7, JP3.4/6/8)” on page 2-8).
Finally, determine the source of encoder or decoder reset, as described in
“AV_RESET Source Jumper (JP9.1/3/5)” on page 2-14.
Before using the interface, follow the procedure in “A-V EZ-Extender
Setup” on page 1-2.
For more information about ADV7179 and ADV7183B, go to
www.analog.com/ADV7179 and www.analog.com/ADV7183B.
Camera Module Interfaces
The Blackfin A-V EZ-Extender has three right-angle connectors (J4,J6,
and P4) with control signals necessary to interface with three camera eval-
uation modules from different manufactures. For a general overview of the
camera interface connections, see Figure 2-1 on page 2-3; for details, see
“A-V EZ-Extender Schematic” on page B-1. Figure 1-1 shows the orienta-
tion of the camera modules as each camera connects to the board.
