BCM3551 - WXGA Digital TV System-on-Chip

WXGA Digital TV System-on-Chip

The BCM3551 combines a cable/terrestrial 4/1024-QAM and 8/16-VSB receiver, an out-of-band QPSK receiver, NTSC demodulator, DVI/HDMI receiver, a transport processor, a digital audio processor, a high-definition (HD) MPEG video decoder, 2D graphics processing, digital processing of analog video and audio, analog video digitizer and DAC functions, stereo high-fidelity audio DACs, a 250-MHz MIPS processor, and a peripheral control unit providing a variety of television control functions.

The cable/terrestrial receiver directly samples a tuner output with an A/D converter. It digitally resamples and demodulates the signal with recovered clock and carrier timing, filters and equalizes the data, and passes soft decisions to an ATSC A/53 and ITU-T J.83 Annex A/B/C compatible decoder. A CEA/EIA-909 smart antenna interface is included on chip.

  • Complete Analog and Digital Television System-on-Chip
  • ATSC and Digital Cable Ready Compatible with ATSC, 4-1024 QAM, out-of-band receivers and Direct CableCARD™ interface
  • Superior ATSC signal reception and demodulation under both static and dynamic multipath conditions.
  • On-chip support to convert all inputs (480i, 480p, 720p, 1080i) to all outputs (480i, 480p, 720p, 1080i) in both digital and analog formats.
