Pin 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; 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)

1. RSET must be a 1% resistor
