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.

ADSP-BF53x EZ-Extender 1 Manual 1-1
1 USING EZ-EXTENDER
After a brief product description, this chapter relates how the extender
interfaces with the compatible boards. The information is presented in the
following sections.
•“Overview” on page 1-1
•“Connecting EZ-Extender” on page 1-2
Overview
The ADSP-BF53x EZ-Extender 1 is a separately sold assembly that plugs
onto the expansion interface of the ADSP-BF53x EZ-KIT Lite evaluation
system. The extender aids the design and prototyping phases of
ADSP-BF53x processor targeted applications.
The board extends the capabilities of the evaluation system by providing a
connection between the Parallel Peripheral Interface (PPI) of the
ADSP-BF53x EZ-KIT Lite board, an Analog Devices High-Speed Con-
verter (HSC) evaluation board, an OmniVision camera evaluation board,
and an LCD display device. Moreover, the extender broadens the range of
the EZ-KIT Lite applications by providing surface mounted (SMT) foot-
prints for breadboard capabilities and access to all of the pins on the
EZ-KIT Lite’s expansion interface.

Connecting EZ-Extender
1-2 ADSP-BF53x EZ-Extender 1 Manual
Connecting EZ-Extender
The following evaluation boards can interface with the EZ-Extender.
•“HSC Boards” as described in the next section
•“OmniVision Camera” as described on page 1-3
•“LCD Interface” as described on page 1-3
HSC Boards
The EZ-Extender can connect to Analog-to-Digital Converter (ADC),
Digital-to-Analog Converter (DAC), and mixed-signal HSC evaluation
boards. Before any connection is made, make sure that you understand its
requirements by familiarizing yourself with the boards’ documentation
and schematics.
For each board type, you need to determine the source of the PPI clock.
To learn about possible clock settings, refer to “Clock” on page 2-8.
It is also necessary to determine the direction of the data and frame syn-
chronization signals. The direction is dependent upon the type of the
board you are connecting to. For example, with ADC boards, it is neces-
sary to set up the data driver on the extender card as receivers. With DAC
boards, the data driver on the extender board needs to be set as transmit-
ters. And, finally, with mixed-signal boards, the direction alters, and a
programmable flag can be used to change the direction in real time. The
frame sync signals are dependent on the external user interface, and the
functionality of the interface must be carefully looked at. For more infor-
mation, refer to “DIP Switches” on page 2-5.
Refer to the HSC examples for any specific jumper settings. Examples are
provided for both the AD9244 and AD9744 boards.

OmniVision Camera
The EZ-Extender 1 allows the OV6630 OmniVision camera evaluation
board to interface with the ADSP-BF53x EZ-KIT Lite evaluation system.
Please note that an on-board data driver is set up as a receiver. The direc-
tion of frame synchronization signals depends on the OmniVision camera.
The OV6630 camera is a CMOS Image sensor that can be connected
directly to the PPI of the ADSP-BF53x Blackfin processor. The connec-
tion allows a digital video stream to be captured by the processor. Since
the PPI interface is a half-duplex interface, it cannot be used for any other
purposes while the Omnivision camera is connected.
For more information, see “OmniVision Interface” on page 2-3. For any
specific jumper settings, refer to the OmniVision example. To learn more
about the OV6630 camera, go to http://www.ovt.com.
LCD Interface
This interface is intended to drive an LCD display device. Therefore, the
on-board data driver should be set up as a transmitter.
While many LCD displays are available, an example is provided for the
Sharp display. Please note that the provided connector includes data and
frame sync pins only. The power for the backlight feature of the LCD
must be provided by the customer.
A 32-pin, right angle FLZ-type connector is provided to connect the data
and control lines of commercially available LCD panels. The part number
of the connector on the EZ-KIT Lite expansion board is
JST32FLZ-SM1-R-TB. The cable connecting the JST part to the data
port on the LCD is available from Parlex Corporation, part number
050-32-76B.

EZ-Extender Hardware Reference
• One OmniVision camera interface connector (J2)
• One LCD interface connector (P8)
Bidirectional drivers connect the Parallel Peripheral Interface (PPI) of the
ADSP-BF53x Blackfin processor to all of the OmniVision and HSC con-
nectors. A clock circuit allows multiple options for PPI interface clocking.
HSC Interface
As mentioned in “Connecting EZ-Extender” on page 1-2, there are three
types of High-Speed Converter evaluation boards supported by the
EZ-Extender:
• Analog-to-Digital Converter boards
• Digital-to-Analog Converter boards
• Mixed-signal boards
The HSC interface employs two connectors, J3 and J4. The J3 connector
is a 40-pin, 0.1 in. spacing, right angle, female socket for interfacing with
ADC evaluation boards. The J4 connector is a 40-pin, 0.1 in. spacing,
straight header intended for interfacing with DAC evaluation boards.
Both connectors provide all the necessary signals to transmit and receive
data to and from HSC evaluation boards.
The RJ45 connector (J1) provides the processor’s SPI signals for program-
ming the internal registers of some high-speed converters.
OmniVision Interface
The OmniVision connector is a 32-pin, 0.1 in. spacing, right angle,
female socket. The connector provides all of the necessary control and
data signals to interface with the OmniVision OV6630AA single-chip
CMOS CIF color digital camera module.

DIP Switches
Direction Control DIP Switch
The PPI interface is bidirectional and half-duplex. A designated DIP
switch, SW1, provides an independent direction control for the data bus
and each of the sync signals, as illustrated in Figure 2-2.
[If the PF0 Programmable Flag is intended for direction control,
ensure the flag is not used for other purposes on the ADSP-BF53x
EZ-KIT Lite board (the motherboard).
When the switch connects a direction control signal to ground (GND), the
corresponding signal (or signals) being controlled is an input. The SW1
DIP switch settings are summarized in Table 2-1, Table 2-2, and
Table 2-3 on page 2-6.
