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.
An external resistor to ground sets all internal timing; a 681k 1% resistor will provide correct timing for
NTSC signals.
Odd/even field output; high during odd fields, low during even fields; transitions occur at start of vert
sync pulse.
Positive supply (5V).
