DESCRIPTION
The TDA7500 is an integrated circuit implementing a
fully digital, integrated and advanced solution to per-
form the signal processing in front of the power am-
plifier and behind the AM/FM tuner or any other audio
source. The chip integrates two 45 MIPs DSP cores:
one for stereo decoding, noise blanking, weak signal
processing and multipath detection and one for
sound processing, Dolby B, echo and noise cancel-
ling for the telephone.
