Color Video Camera Synchronizing Signal Generator LSI
Pin Assignment
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
