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; 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)
