NOTES:
2. The composite sync output reproduces all the video input sync pulses, with a propagation delay.
3. Vertical sync leading edge is coincident with the first vertical serration pulse leading edge with a propagation delay.
4. Horizontal sync output produces the “H” pulses of nominal width of 5µs. It has the same delay as the composite sync.
