TDA7512F is an FM car-radio tuner IC with intelligent selectivity system (ISS). It features RF AGC generation by RF and IF detection, I/Q mixer for 1st FM IF 10.7 MHz with image rejection, 2 programmable IF-gain stages, mixer for 2nd IF 450 kHz, internal 450 kHz bandpass filter with three bandwidths controlled by ISS, fully integrated FM-demodulator with noise cancellation, and more.
The TDA7512F is a high-performance tuner circuit designed for FM car radios. It integrates a mixer, IF amplifier, demodulator, quality detection, ISS filter, and PLL synthesizer on a single chip using BiCMOS technology to minimize external components.
The device features an Intelligent Selectivity System (ISS) to cancel adjacent channel and noise influences, a VCO for a world tuning range, and a high-performance fast PLL for RDS systems. It includes quality detection information available as analog signals for level, deviation, adjacent channel, and multipath.
