1-4 Blackfin A-V EZ-Extender Manual
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 the video devices, configure the two-wire interface sig-
nals (see “TWI Source Selection Jumpers (JP3.3/5/7, JP3.4/6/8)” on
page 2-7). Finally, determine the source of the encoder or decoder reset
(see “AV_RESET Source Jumper (JP9.1/3/5)” on page 2-14.)
Before using the interface, follow the steps in “A-V EZ-Extender Setup”
on page 1-1.
Example programs demonstrating the capabilities of the analog video
interface are included in the A-V EZ-Extender installation directory.

Camera Module Interfaces
The Blackfin A-V EZ-Extender has three right-angle connectors (J4, J6,
and
P4) with the control signals necessary to interface with three different
manufactures camera evaluation modules. For a general overview of the
camera module interface connections, see Figure 2-1 on page 2-4. For
more detailed information, see “A-V EZ-Extender Schematic” on
page B-1. Figure 1-1 shows the orientation of the camera modules, as each
camera connects to the board.
The
J6 connector is designated for a Micron camera sensor evaluation
module. The interface has been tested with the Micron MT9V022 camera
evaluation module. For information about Micron camera sensors and
evaluation boards, go to
http://www.micron.com.
The J4 connector is designated for an OmniVision camera sensor evalua-
tion module. The interface has been tested with the OmniVision
OV6630AA camera evaluation module. For information about OmniVi-
sion camera sensors and evaluation boards, go to
