FUNCTION

An input pin for the reference horizontal signal to

RPI

Horizontal comparison

ICD

the phase comparator. Connect to HD

—

input

when comparator is used. The polarity of RPI se-

lects with CPCH (pin 11),

A horizontal synchronous pulse obtained by dividing

4FSI (pin 3).

At NTSC mode

: dividing into 1/910

At PAL mode

: dividing into 1/1 135 4FSI

SCHD

–

ordinarily and dividing into

137 4FSI during one ho-

rizon tal period within the V

blanking.

At SECAM mode : dividing into 1/1 128

Horizontal comparison

An input pin for comparison horizontal signal to the

CPI

–

input

phase comparator. Connect to SCHD (pin 15) when

comparator is used,

GND

—

Ground

A grounding pin.
