Timing Diagram
Notes:
b. The composite sync output reproduces all the video input sync pulses, with a propagation delay.
c. Vertical sync leading edge is coincident with the first vertical serration pulse leading edge, with a propagation delay.
d. Odd-even output is low for even field, and high for odd field.
e. Back porch goes low for a fixed pulse width on the trailing edge of video input sync pulses. Note that for serration pulses during
vertical, the back porch starts on the rising edge of the serration pulse (with propagation delay).
f. Horizontal sync output produces the true “H” pulses of nominal width of 5µs. It has the same delay as the composite sync.
