Product Summary

The BCM3349KPB is an advanced qamlink DOCSIS 2.0 high-performance, single-chip cable modem. It combines an RF receiver with an advanced QAM and S-CDMA demodulator, an advanced QAM transmitter, a complete DOCSIS 2.0 Media Access Controller (MAC), a 200-MHz MIPS32 communication processor, a 16-bit, 100-MHz SDRAM interface, 10/100 Ethernet MAC with integrated transceiver and MII Interface, and a USB MAC with integrated transceiver. The BCM3349KPB directly samples a tuner output with a 11-bit A/D converter and input ACG amplifier. The BCM3349KPB digitally resamples and demodulates the signal with recovered clock and carrier timing, filters and equalizes the data and passes soft decisions to an ITU-T J.83 Annex A/B/C compatible decoder.
