QAMLink® DOCSIS®/EuroDOCSIS™ 2.0 Single-Chip Cable Modem

Currently Viewing:

The BCM3349 is a highly integrated DOCSIS®/EuroDOCSIS™ 2.0-based cable modem chip that addresses the performance and reliability requirements of high-speed data, voice and gateway modem designs.
The BCM3349 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. Tight integration reduces component count, improves assembly process and lowers overall system cost.


  • Integrates a high-performance 200 MHz MIPS32® CPU
  • Advanced RF and control interface to silicon tuner for DOCSIS/EuroDOCSIS solutions
