Advanced two IC chipset for DVB on satellite reception

A QPSK chipset applicable for digital video broadcast (DVB) signals from a satellite is described. It consists of two ICs, a bipolar I/Q demodulator with an on-chip AGC and delayed tuner AGC and a CMOS QPSK processor device with an ADC, clock and carrier recovery, Viterbi decoding and Reed-Solomon forward error correction.
