MC1372 Color TV Video Modulator

Pin 1 - Clock Output Provides a rectangular ptJise output waveform with frequency equal to the chrominance subcarrier oscillalor. This output" capable of driving one LS-TTL load. Pin 2- Oscillator Input Color subcarrier oscillator feedback mput. Signal from Pin 11- Vee Positive supply voltage Pin.

® MOTOROLA MC1372 COLOR TV VIDEO MODULATOR an mtegrated circuit used to generate an RF TV signal from baseband color-difference and luminance signals. The MC1372 contains a chroma subcamer oscillator, a lead and COLOR TV VIDEO MODULATOR CIRCUIT SILICON MONOLITHIC INTEGRATED CIRCUIT lag network, a quasi-quadrature suppressed carrier DSB chroma modulator, an RF oscillator and modulator, and an LSTTL compatrble clock driver with adjustable duty cycle. The MC1372 is a companion part to the MC6.

MC1372 Features

* 3 are switched in trans1stors 022 through 025 and the resultant signal voltage is developed across R49. This signal has the phase and frequency of the oscillator signal at the emitter of 021. The amplitude is proportional to the differential input signal applied between
