TDA7528 AM/FM car radio Front-End receiver for IF sampling tuners

The TDA7528 is a front-end module for use in car radio receivers with digital IF processing, using the STA3004, respectively the STA3005 backend IC.

Its field of use includes all the current radio broadcast services in the range of 50kHz to 163MHz for AM radio, FM radio and US weather band. Digital standards such as DRM and HD radio can also be handled. A single supterheterodyne architecture with 10.7 MHz IFfrequency provides high dynamic range.

The IMR mixer has separate input and output stages for AM frequency bands up to 30 MHz and for FM frequencies above 30 MHz.

The integrated AM-preamplifier and the fully integrated low-pass filter enable low cost applications. Two FM inputs with different noise / IP3 parameter, provide full flexibility for the prestage circuitry. Each mixer output is able to drive two IF-filters, which can be selected by the different IF-amplifier inputs.

The fast tuning PLL controls two different VCO, which are designed to operate without frequency overlap.
