MN676011NPS
NTSC Color Camera Synchronizing Signal Generator LSI
Overview
The MN676011NPS 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 os-
cillator circuit and divides that frequency to generate the
horizontal synchronizing signal f_H (15.7 kHz), the vertical
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 and the burst signal gated with the burst flag
(BF) pulse.
It includes a vertical reset (VR) input pin for resetting
the leading edge of the vertical synchronizing pulse (VP)
with the falling edge of the input signal. It also includes
separate clock input pins for the color subcarrier frequency
signal circuits and the synchronizing signal circuits to
permit synchronization with such external synchroniz-
ing LSIs as the MN6761S.
