1 / 45 page June 2009 Doc ID 12668 Rev 2 1/45 1 TDA7512F FM car-radio tuner IC with intelligent selectivity system (ISS) Features FM part ■ 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 Additional features ■ VCO for world tuning range ■ High performance fast PLL for RDS-system ■ IF counter with search stop signal ■ Quality detector for level, deviation, adjacent channel and multipath ■ Quality detection informations as analog signals external available ■ ISS (intelligent selectivity system) for cancellation of adjacent channel and noise influences ■ Adjacent channel mute ■ Fully electronic alignment ■ All functions I2C bus controlled Description The TDA7512F is a high performance tuner circuit for FM car-radio. It contains mixer, IF amplifier, demodulator, quality detection, ISS filter and PLL synthesizer with IF counter on a single chip. Use of BiCMOS technology allows the implementation of several tuning functions and a minimum of external components. LQFP64 Table 1.
