Pin Descriptions
PIN NUMBER
PIN NAME
PIN 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 vertical sync is the start of the vertical period.
4
Gnd
Supply ground
5
HD
Low when input horizontal frequency is greater than 20kHz.
6
CSET
(An external capacitor to ground); bypass pin for internal bias generator.
7
Horizontal Output
Horizontal output; falling edge active
8
VDD
Positive supply
