ADVANCED  
MULTI–STANDARD  
VIDEO/SOUND IF  
The MC44302A is a multi–standard single channel TV Video/Sound IF  
and PLL detector system specifically designed for use with all standard  
modulation techniques including NTSC, PAL, and SECAM. This device  
enables the designer to produce a high quality IF system with a minimum  
number of external components.  
SEMICONDUCTOR  
TECHNICAL DATA  
The MC44302A contains a high gain video IF with an AGC range of 80 dB,  
enhanced phase–locked loop carrier regenerator for low static phase error,  
doubly balanced full wave synchronous video demodulator featuring wide  
bandwidth positive and negative video outputs with extremely low differential  
gain and phase distortion, video AFT amplifier, multistage sound IF limiter  
with FM quadrature detector and AFT for self tuning, AM sound detector,  
constant and variable audio outputs, dc volume control for reduced hum and  
noise pickup, unique signal acquisition circuit that prevents false PLL lockup  
and AFT push out, horizontal gating system with sync separator and  
phase–locked loop circuitry for self–contained RF/IF AGC operation, RF  
AGC delay circuitry, and programmable control logic that allows operation in  
NTSC, and PAL SECAM systems. This device is available in wide body 28 pin  
dual–in–line and surface mount plastic packages.
