PIN FUNCTION

Sharing pin is bold faced in name and explains the feature shown.

1.1

Video Input Interface

The video input is based on the ITU-R BT.656 format. The horizontal synchronization signal, and the vertical

synchronization signal, the field index can be used without using SAV and EAV to provide at ITU-R BT. 656, too.

Video Output Interface

The video output is based on the ITU-R BT.656 format. It is able to output horizontal and vertical synchronization

signals with SAV/EAV. These synchronization signals are chosen output by the firmware. These ports become GPO

until the firmware initializes after hardware reset.

At the time of the odd field, OVVSYNC falls in the 4th clock after falling of OVHSYNC.

At the time of the even field, OVVSYNC falls in to the H/2+4th clock the OVHSYNC falling.
