FUNCTION
Composite sync pulse output. Sync pulses start on a falling edge and end on a rising edge.
AC coupled composite video input. Sync tip must be at the lowest potential (Positive picture phase).
Vertical sync pulse output. The falling edge of Vert Sync is the start of the vertical period.
Supply ground.
Burst/Back porch output. Low during burst portion of composite video.
An external resistor to ground sets all internal timing. 681k, 1% resistor will provide correct timing
for NTSC signals.
Odd/Even field output. Low during odd fields, high during even fields. Transitions occur at start of
