MN67603NS

The MN67603NS is a CMOS LSI that generates NTSC color camera synchronizing signals as defined by the EIA RS-170A standard.

MN67603NS features a built-in 4fSC (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.

MN67603NS also divides the 4fSC clock signal frequency by four to generate the color subcarrier frequency signals SC1 and SC2.

MN67603NS 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.It also includes separate clock input pins for the color subcarrier frequency signal circuits and the synchronizing signal circuits to permit synchronization with such external synchronization LSIs as the MN6761S.
