BCM3551

Description

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 BCM3551 directly samples a tuner output with an A/D converter. BCM3551 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.
