Abstract :
The state of set-top-box integration is advanced to achieve true system on a chip capability. The device integrates a universal physical-layer transceiver, a MIPS R3000 CPU core, a MPEG-2 audio and video decoder, an analog video decoder, a graphics engine, a video encoder, a DAVIC MAC and a set-top box peripherals module. The physical-layer transceiver is enhanced to achieve an improved bit error rate (BER) performance, by doubling the feed-forward taps of the equalizer, increasing word-length precision in the filters and equalizer, and adding filtering in the tracking loops.
