Horizontal External Sync Source for Sync Separator A. This signal may be pure HSYNC or CSYNC.
Vertical External Sync Source for Sync Separator A
Sync Separator filter capacitor. Connect a 0.056µF capacitor between this pin and analog ground.
Horizontal Sync Output for Sync Separator A
Vertical Sync Output for Sync Separator A
Field Flag for Sync Separator A. Low = odd field, high = even field.
External Clamp Timing Pulse for Sync Separator A (for timed back porch clamping)
Horizontal External Sync Source for Sync Separator B. This signal may be pure HSYNC or CSYNC.
Vertical External Sync Source for Sync Separator B
Sync Separator filter capacitor. Connect a 0.056µF capacitor between this pin and analog ground.

Analog Input. Chroma Reference Level for DC-Restore when A
the midpoint voltage of the C signal (S-Video) and the Pb, Pr signals (Component video) for Channel A when
the gain is set to x2. When using the YPbPr inputs in YPbPr mode, this DC voltage sets the clamp voltage
of the Pr/R and Pb/B signals for Channel A. This input is typically tied together with V
driven with the same voltage.
Analog Input. Chroma Reference Level for DC-Restore when A
midpoint voltage of the C signal (S-Video) and the Pb, Pr signals (Component video) for Channel A when
the gain is set to x1. When using the YPbPr inputs in YPbPr mode, this DC voltage sets the clamp voltage
of the Pr/R and Pb/B signals for Channel A. This input is typically tied together with V
driven with the same voltage.
