Abstract

This paper describes a single digital IC that performs the digital demodulation, clock recovery, carrier recovery, Viterbi decoding, de-interleaving, and Reed Solomon decoding for digital satellite delivery of video, audio and data. The chip performs up to 60 Mega-bits per second QPSK decoding, covering both the Digital Video Broadcast Satellite (DVBS) standard in Europe and the Digital Satellite System (DSS) in the US. The 0.5 μm CMOS chip contains 504,000 transistors and 56 Kbits of memory in 71 mm². In addition to QPSK, the chip decodes up to 256 QAM with an external equalizer for cable and terrestrial applications
