MN67621F Datasheet, PDF (1/11 Pages) Panasonic Semiconductor – Color Video Camera Synchronizing Signal Generator LSI

For Video Equipment
MN67621F
Color Video Camera Synchronizing Signal Generator LSI
Overview
The MN67621F generates color video camera synchro-
nizing signals for the NTSC, PAL, and SECAM video
systems.
It divides the reference frequency to generate the horizon-
tal synchronizing signal f_H , the vertical synchronizing
signal f_V , and the composite synchronizing signal.
A built-in 4f_SC crystal oscillator circuit divides the fre-
quency by four to generate the color subcarrier frequency
signals SC1 and SC2.
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.
Applications
Color video cameras
