® 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 MC6847 Video Display Generator, providmg and accepting the correct de interconnection levels. This device may also be used as a general-purpose modulator wtth a variety of vtdeo signal generating devices such as video games, test equipment, video tape recorders, etc. • • .
