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 4fSC (14.31818 MHz) crystal oscil-
lator circuit and divides that frequency to generate the
horizontal synchronizing signal fH (15.7 kHz), the verti-
cal synchronizing signal fV (60 Hz), and the composite
synchronizing signal.
It also divides the 4fSC 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.
Features
Power-saving CMOS synchronization signal
generator (conformed to EIA RS-170A standard)
Built-in 14.31818 MHz clock generator
10 signal outputs including horizontal and vertical
synchronization signals and color subcarrier
frequency signals
