TDA7529 is a high performance RF front-end launched by ST company, which can be used for AM/FM DSP car radio with 10.7 MHz IF sampling. The chip integrates VCO, PLL, I/Q mixer, low noise IF amplifier, IF switch and other functions. Using BiCMOS technology, it can implement multiple tuning functions and reduce the number of external components.
The document describes the TDA7529, an RF front-end designed for AM/FM DSP car-radio applications featuring 10.7 MHz IF sampling. The chip integrates a fully integrated VCO, high-performance PLL synthesizer, mixers for FM and AM, and various AGC stages on a single BICMOS chip.
Key features include a Q mixer for FM IF with image rejection, an integrated balun to save external components, and electronic alignment for preselection stages. The device operates from a single 5 V supply and supports alternative frequency control signals for DSP integration.
