1 / 7 page November 2006 Rev 2 1/7 7 TDA7515 RF front-end for AM/FM-DSP car radios with IF sampling Features ■ RF AGC generation by RF and IF detection ■ I/Q Mixer for FM IF 10.7MHz with image rejection and programmable IF tank adjust for FM and AM ■ Preamplifier and mixer for IF 10.7MHz AM upconversion ■ VCO and programmable divider for “world receiver” ■ Programmable controlled IF-gain stage ■ High performance fast PLL for RDS-system ■ Electronic alignment for the preselection stages ■ All functions bus-controlled Description The front-end is a high performance tuner circuit for AM/FM - DSP car radios with 10.7MHz - IF sampling. It contains mixer and IF amplifiers for AM and FM, VCO and PLL synthesizer on a single chip. Use of BICMOS technology allows the implementation of several tuning functions and a minimum of external components.
