RESET

Input

System Reset Input, Active Low. A minimum low reset pulse width of 5 ms is required

to reset the ADV7181D circuitry.

52

ALSB

Input

set to Logic 0, this pin sets the address for a write to Control Port 0x40 and the readback

address for VBI Port 0x21. When set to Logic 1, this pin sets the address for a write to

Control Port 0x42 and the readback address for VBI Port 0x23.
