Abstract: An integrated circuit is embodied on a monolithic substrate and incorporates a tuning module of the direct sampling type that is able to receive satellite digital television analog signals composed of several channels, as well as several channel decoding digital modules connected at the output of the tuning module so as to deliver respectively simultaneously several streams of data packets corresponding to several different selected channels.

Abstract: The component, fully integrated onto a monolithic substrate, includes a tuner, a demodulator, and a channel decoder. The overall filtering is carried out in two parts, a baseband analog filtering and a digital Nyquist filtering removing the information of adjacent channels. It outputs a stream of MPEG data.
