MN67621F
Color Video Camera Synchronizing Signal Generator LSI
Overview
The MN67621F generates color video camera synchronizing signals for the NTSC, PAL, and SECAM video systems. It divides the reference frequency to generate the horizontal synchronizing signal fH , the vertical synchronizing signal fV , and the composite synchronizing signal. A built-in 4fSC crystal oscillator circuit divides the frequency by four to generate the color subcarrier frequency signals SC1 and SC2.
