Broadcom Corporation - BCM3517 - ATSC/VSB Digital Cable Ready DTV Receiver

The BCM3517 is an ATSC/VSB Digital Cable Ready DTV receiver that contains a digital receiver that is compatible with both North American digital cable Television and digital terrestrial broadcast Television standards. This receiver is capable of receiving all standard-definition and high-definition digital formats (SDTV/HDTV). The on-chip Audio decoder is fully compliant with the BTSC Audio standard. An out-ofband QPSK receiver is also contained to meet the needs of the CableCard specification. The BCM3517 's digital receiver accepts an Analog signal centered at the standard Television IF frequencies, and amplifies and digitizes this signal with an integrated Programmable Gain Amplifier and 12-bit A/D converter The output of the A/D is sent to the receiver and Demodulator The digital receiver consists of a QAM Demodulator and a VSB Demodulator Each Demodulator contains adaptive Filters that remove multi-path propagation effects, NTSC co-channel interference, and RFI interference. The output of the VSB Demodulator goes to an ATSC A/53 coding Forward Error Corrector (FEC), with integrated trellis and Reed-Solomon decoder. The output of the QAM Demodulator goes to an ITUT J.83 Annex A/B/C coding FEC. The output of either QAM or VSB FEC is delivered in either parallel or serial MPEG-2 transport format.
