A digital television demodulator IC with 256 tap equalizer

The single-chip digital demodulator (AV8100) performs all digital demodulation and forward error correction functions in a digital TV receiver, High Definition TV (HDTV) receiver and related applications. The device conforms to the ATSC Digital Television standard for the reception of terrestrial broadcast over a 6 MHz channel using 8-VSB modulation. This CMOS chip performs matched filtering, timing recovery, carrier recovery, equalization, and forward error correction (FEC) on digitized IF pass-band samples at its input. The output from the device is an error corrected MPEG-2 transport stream with low jitter.
