EZ-Extender Interfaces
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
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.

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
