Timing Diagrams
NOTES:
10. Vertical sync leading edge is coincident with the first vertical serration pulse leading edge, with a propagation delay.
12. 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
11. Odd-even output is low for even field, and high for odd field.
SIGNAL 1a. COMPOSITE VIDEO INPUT, FIELD ONE
SIGNAL 1b. COMPOSITE SYNC OUTPUT, PIN 1
SIGNAL 1c. VERTICAL SYNC OUTPUT, PIN 3
SIGNAL 1d. ODD-EVEN OUTPUT, PIN 7
SIGNAL 1e. BACK PORCH OUTPUT, PIN 5
9. The composite sync output reproduces all the video input sync pulses, with a propagation delay.
back porch starts on the rising edge of the serration pulse (with propagation delay).
