Overview
For Video Equipment 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.
Pin Assignment Features Supports CCDs with 420, 510, 590, and 670 H pixels Supports NTSC, PAL, and SECAM video systems PAL system 25Hz offset Includes built-in oscillator circuit using external crystal Generates 14 signals, including the horizontal and vertical synchronizing signals and the color subcarrier frequency signals.
