Description

The TDA7546 multichip module combines in a single compact (14X14mm) 80-pin package the functionalities of a state-of-the-art FM receiver and RDS processor, exploiting one single 10.25MHz crystal reference.

The following two devices are included

– TDA7512F, high performance car-radio FM tuner with high-speed on-chip PLL and variable-bandwidth IF filter (ISS)

– TDA7333N, fully digital RDS data decoder with with on-chip group and block synchronization and error detection/correction.

Both chips are I2C-bus controlled.
