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 I
2
C-bus controlled.
