MC1372 Datasheet | Motorola Semiconductor

® MOTOROLA 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 patrble clock driver with adjustable duty cycle. The MC1372 is a panion 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. - - .~ '~~ ~ ~ ~ Duty P SUFFIX PLASTIC PACKAGE CASE 646-05 Single 5.0 Vdc Supply Operation for NMOS and TTL patibility Minimal External ponents Pin Connections - - - - patible with MC6847 Video Display Generator Sound Carrier Addition Capability Modulates Channel 3 or 4 Carrier with Encoded Vrdeo Signal - - - - Low Power Dissipation Linear Chroma Modulators for High Versatrlity posrte Vrdeo Signal Generation Capability Ground-Referenced Video Prevents Overmodulation Chromtnance input Lum1nance Input Chror T;a 1'0odu!ator Output FIGURE 1- BLOCK DIAGRAM Color 8 Input Lum1flance 1npi..-t...
