1 EZ-EXTENDER INTERFACES
The Blackfin EZ-Extender board offers the following interfaces.
•“ADC and Mixed-Signal HSC Interface” on page 1-1
•“DAC HSC Interface” on page 1-2
•“Camera Interface” on page 1-3
•“LCD Interface” on page 1-4
The following sections describe each extender interface.
ADC and Mixed-Signal HSC Interface
The Blackfin EZ-Extender can connect to an analog-to-digital converter
(ADCs) and a mixed-signal HSC evaluation board via the
ADC/mixed-signal HSC interface. The ADC/mixed-signal HSC interface
consists of a 40-pin female header, which contains all of the control and
data signals necessary to transfer data between the processor’s parallel
peripheral interface (PPI) and the HSC evaluation board. Additionally,
the extender provides a RJ-45 connector, which contains all of the serial
peripheral interconnect (SPI) signals necessary to configure the control
registers of capable HSC converters. For a block diagram of this interface,
see Figure 2-1 on page 2-2.
Before using the Blackfin EZ-Extender, familiarize yourself with the docu-
mentation and schematics of the target board and the EZ-KIT Lite. For
example, on the EZ-KIT Lite, it may be necessary to disable other devices
on the PPI, route the PPI clocks, and disable the push buttons.

DAC HSC Interface
1-2 Blackfin EZ-Extender Manual
To configure the Blackfin EZ-Extender to connect to an ADC or
mixed-signal HSC evaluation board, first determine the source of the PPI
clock. To learn about possible clock settings, refer to “Clock Routing
Switch (SW2)” on page 2-5. It is also necessary to determine the direction
of the data and frame synchronization signals. The direction is dependent
upon the type of the board to which you connect. With ADC boards, it is
necessary to set up the data driver on the extender as a receiver. With
mixed-signal boards, the data direction can change and a programmable
flag is used to change the direction in real time. The frame sync signals are
dependent on the external user interface; thus, the functionality of the
interface must be taken into consideration. For more information, refer to
“System Architecture” on page 2-1 and “DIP Switches and Jumpers” on
page 2-4.
Refer to the Analog Devices Web site at www.analog.com/EX1-Extender
for more information about the daughter card. To learn more about
Analog Devices data converters, go to www.analog.com.
DAC HSC Interface
The Blackfin EZ-Extender can connect to digital-to-analog converter
HSC evaluation boards via the DAC HSC interface. The DAC HSC
interface consists of a 40-pin male header, which contains all of the con-
trol and data signals necessary to transfer data from the processor’s PPI to
the DAC evaluation board. Your extender kit includes the cable used to
make a connection. For more information about this interface, see
Figure 2-1 on page 2-2.
Before using the Blackfin EZ-Extender, familiarize yourself with the docu-
mentation and schematics of the target board and the EZ-KIT Lite. For
example, on the EZ-KIT Lite, it may be necessary to disable other devices
on the PPI, route the PPI clocks, and disable the push buttons.
To configure the Blackfin EZ-Extender to connect to a DAC evaluation
board, first determine the source of the PPI clock. To learn about possible

Blackfin EZ-Extender Manual 1-3
EZ-Extender Interfaces
clock settings, refer to “Clock Routing Switch (SW2)” on page 2-5. It is
also necessary to determine the direction and source of the data and frame
synchronization signals. If your processor holds more than one PPI, the
DAC interface allows you to communicate with either PPI0 or PPI1 of the
processor. The direction of the frame sync signals is dependent on the tar-
get; thus, the functionality of the interface must be taken into
consideration. For more information, refer to “System Architecture” on
page 2-1 and “DIP Switches and Jumpers” on page 2-4.
Example programs can be found in the software installation directory. To
learn more about Analog Devices data converters, go to www.analog.com.
Camera Interface
The Blackfin EZ-Extender camera interface is a right-angle 32-pin con-
nector with control signals compatible to the ITU-R BT.656 camera
interface specification. Specifically, the extender’s camera interface is
directly compatible with camera interface boards, such as the Omnivision
OV6630AA evaluation module (this part is no longer available). To learn
more about the OV6630AA evaluation module, go to
http://www.ovt.com. For a block diagram of the camera interface, see
Figure 2-1 on page 2-2.
Before using the Blackfin EZ-Extender, familiarize yourself with the docu-
mentation and schematics of the target board and the EZ-KIT Lite. For
example, on the EZ-KIT Lite, it may be necessary to disable other devices
on the PPI, route the PPI clocks, and disable the push buttons.
To configure the Blackfin EZ-Extender to connect to a camera, first deter-
mine the source of the PPI clock. To learn about possible clock settings,
refer to “Clock Routing Switch (SW2)” on page 2-5. It is also necessary to
set the direction of the data and the frame sync signals. The direction of
frame synchronization signals depends on the camera’s configuration.

LCD Interface
1-4 Blackfin EZ-Extender Manual
The data must be set as an input to the PPI port. For more information,
refer to “System Architecture” on page 2-1 and “DIP Switches and Jump-
ers” on page 2-4.
LCD Interface
The LCD interface is intended to drive an LCD display device. A 32-pin,
right-angle FLZ-type connector is provided to connect the data and con-
trol lines of commercially available LCD panels. For a block diagram of
this interface, see Figure 2-1 on page 2-2.
A timing and functional analysis is required to determine if a specific LCD
can connect to the Blackfin EZ-Extender. An example of a display which
does connect to the extender is the Sharp LQ058T5DRQ1 display (this
display is no longer available).
Please note that the power for the backlight feature of the LCD must be
provided by the customer. Information on the backlight inverter module
(part number LXM1614-14-11) needed to connect to the LCD panel is
available at http://www.microsemi.com/en/sites/
default/files/LXM1614-14-11.pdf. The part number of the connector on
the EZ-Extender 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).
Before using the Blackfin EZ-Extender, familiarize yourself with the docu-
mentation and schematics of the target board and the EZ-KIT Lite. For
example, on the EZ-KIT Lite, it may be necessary to disable other devices
on the PPI, route the PPI clocks, and disable the push buttons.
To configure the EZ-Extender to connect to the LCD interface, first
determine the source of the PPI clock and the source and direction of the
data and frame sync signals. If your target processor holds more than one
PPI, the LCD interface allows you to communicate with either PPI0 or
