As shown in Figure 47, the ADV7610
controlled by the output control block in the CP block.
Primary:
•
Horizontal synchronization timing reference output on the HS pin
•
Vertical synchronization timing reference output on the VS/FIELD/ALSB pin
•
DE (indicates active region) shared with the FIELD pin
Secondary:
•
Field timing reference output on the DE pin or as a secondary signal on the VS/FIELD/ALSB pin
Timing reference signals with shared pins are controlled via I

The user can program the primary and secondary synchronization signals, repositioning them in order to control the display area, as
shown in Figure 48.
CP can output the following three primary and one secondary synchronization signals, which are
2 C.
