MC44302A

The MC44302A is a multistandard single channel TV Video/Sound IF and PLL detector system specifically designed for use with all standard modulation techniques including NTSC, PAL, and SECAM. MC44302A enables the designer to produce a high quality IF system with a minimum number of external components.

The MC44302A contains a high gain video IF with an AGC range of 80 dB, enhanced phaselocked 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 phaselocked loop circuitry for selfcontained RF/IF AGC operation, RF AGC delay circuitry, and programmable control logic that allows operation in NTSC, and PAL SECAM systems. MC44302A is available in wide body 28 pin dualinline and surface mount plastic packages.
