Video inputs from camera or other source. NOTE: This is also the Y
(Luma) input for S-VHS and HI-8 systems.
C (Chroma) inputs for S-VHS and HI-8 systems. In NTSC systems, this
pin should be tied to its respective Y input.
Data Threshold bypass input.
SYNC Threshold bypass input.
Clamp Threshold bypass input.
Video output. This is also the Y (Luma) output in S-Video mode.
C (Chroma) output for S-VHS and HI-8 systems.
Color Frame A/B input. This input is self biased (See Applications).
