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 oscillator circuit and divides that frequency to generate the horizontal synchronizing signal fH (15.7 kHz), the vertical 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.
