3 GENERAL DESCRIPTION
The Philips SAA3500H is a Digital Audio Broadcast (DAB)
channel decoder according to the ETSI specification
ETS 300 401. The SAA3500H is a successor to the Philips
FADIC and SIVIC chip set and provides an IF ADC, digital
mixer, full DAB ensemble demodulation and decoding as
well as time and frequency synchronization functions.
Because of the full-speed Viterbi decoding capacity and a
high-speed receiver data output interface, DAB data
reception is not limited by the SAA3500H channel
decoder.
