Overview

For Video Equipment 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 4fSC (14.
31818 MHz) crystal oscillator circuit and divides that frequency to generate the horizontal synchronizing signal fH (15.
7 kHz), the vertical synchronizing signal f V (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 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 synchronizing LSIs as the MN6761S.
