Pin Descriptions

PIN NUMBER

PIN NAME

FUNCTION

1

Composite Sync Out

Composite sync pulse output; sync pulses start on a falling edge and end on a rising edge.

2

Composite Video In

AC coupled composite video input; sync tip must be at the lowest potential (positive picture phase).

3

Vertical Sync Out

Vertical sync pulse output; the falling edge of vert sync is the start of the vertical period.

4

GND

Supply ground.

5

Burst/Back Porch Output Burst/back porch output; low during burst portion of composite video.

6

RSET (Note 1)

An external resistor to ground sets all internal timing; a 681k 1% resistor will provide correct timing for

NTSC signals.

7

Odd/Even Output

Odd/even field output; high during odd fields, low during even fields; transitions occur at start of vert

sync pulse.

8

VDD 5V

NOTE:

1. RSET must be a 1% resistor.

Positive supply (5V).
