Patent ID: 7796197

Claim:
An electronic component, comprising: an integrated circuit embodied on a single monolithic substrate and comprising each of the following components fabricated on that single monolithic substrate: a tuning module of the zero intermediate frequency dual upconversion then downconversion type possessing an input that receives a digital terrestrial or cable television analog signal composed of several channels and a first upconversion frequency transposition stage and a second zero intermediate frequency downconversion frequency transposition stage; a bandpass filter of the bulk acoustic wave type disposed between the first and second frequency transposition stages and delivering a filtered analog signal containing the information conveyed by a desired channel and adjacent channels information; a baseband filtering stage disposed on two quadrature output paths of the second zero intermediate frequency downconversion frequency transposition stage for performing a first filtering of the adjacent channels information; a multibit analog/digital conversion stage linked to the output of the baseband filtering stage, a digital block comprising a stage for correcting defects in phase- and amplitude-pairing of the two quadrature paths, and a channel decoding digital module (DM), linked to the output of the defects correcting stage, and comprising a demodulation stage, a digital filtering stage for eliminating the said adjacent channels information, and an error correcting stage for delivering a stream of data packets corresponding to the information conveyed by the desired channel; and a circuit for determining the central frequency of the bulk acoustic wave filter and controlling the first upconversion frequency transposition stage in response to the determined central frequency to place the desired channel at the determined central frequency.
