MN67603NS
NTSC Color Camera Synchronizing Signal Generator LSI
Overview
The MN67603NS is a CMOS LSI that generates NTSC
color camera synchronizing signals as defined by the EIA
RS-170A standard.
It features a built-in 4f_SC (14.31818 MHz) crystal oscil-
lator circuit and divides that frequency to generate the
horizontal synchronizing signal f_H (15.7 kHz), the verti-
cal synchronizing signal f_V (60 Hz), and the composite
synchronizing signal.
It also divides the 4f_SC clock signal frequency by four
to generate the color subcarrier frequency signals SC1
and SC2.
It includes a vertical reset (VR) input pin for resetting
the leading edge of the V-SERATION (3H) signal with
the falling edge of the input signal.
It also includes separate clock input pins for the color
subcarrier frequency signal circuits and the synchroniz-
ing signal circuits to permit synchronization with such
external synchronization LSIs as the MN6761S.
