ADV7390/ADV7391/ADV7392/ADV7393
Mode 3—Master/Slave Option (Subaddress 0x8A = X X X X X 1 1 0 or X X X X X 1 1 1)
In this mode, the ADV739x accepts or generates horizontal synchronization and odd/even field signals. When HSYNC is high, a
transition of the field input indicates a new frame, that is, vertical retrace. The ADV739x automatically blanks all normally blank lines as
per CCIR-624. HSYNC and VSYNC are output in master mode and input in slave mode on the HSYNC and VSYNC pins, respectively.
