VDEC1 board is attached to a system board,
and the system board is driving as outputs the
same signals the VDEC1 is driving, damage to
the VDEC1 and system board will result.
Before attaching the VDEC1 to a system
board, ensure that any power-on auto-
loaded configuration drives the Hirose pins
correctly. Otherwise, ensure the system
board powers on in a reset mode, not
driving the Hirose pins as outputs.
Once the VDEC1 board is attached to a
system board, the ADV7183B chip must be
programmed (via its I
2
C
®
compatible port) for a
specific operating mode before output video
data is available. Please refer to the
ADV7138B data sheet for information on
programming various operation modes.
After an operating mode has been selected, a
video source can be attached to the
appropriate video input connector, and output
digital video data will be available.
Hirose Connector Pinout
The VDEC1 contains a 100-pin Hirose FX2
socket connector that mates with a
corresponding Hirose plug connector on a
system board. Pin1 of the socket connector
attaches to pin1 of the plug connector. Thus, to
generate a pin connection list for a given
system board, the signal definitions in the
following table can be directly mapped to the
signal definitions on the system board (e.g.,
the signal name on VDEC1 pin5 maps directly
to the signal on the system board pin5).
