| 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 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. LQFP44 Description The front-end is a high performance tuner circuit for AM/FM - DSP car radios with 10.7MHz - IF sampling.
