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.

LQFP80

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.
