Broadcom's DOCSIS 3.1 Cable Modem Chip Tops 1 Gbps

Broadcom has begun sampling a DOCSIS 3.1 cable modem system-on-a-chip (SoC) that support access speeds of over a Gigabit per second (Gbps). The company said its new BCM3390 cable modem SoC delivers video content with a nearly 50 percent increased efficiency on existing spectrum allocations and allows for the delivery and use of a new range of content and services. Key attributes include:

  • Full compliance with full DOCSIS 3.1 specification
  • Two OFDM 196 MHz downstream channels
  • 32 single-carrier DOCSIS 3.0 QAM downstream channels
  • Two 96 MHz OFDM-A upstream channels
  • Eight single-carrier DOCSIS 3.0 QAM upstream channels
  • Includes full software support for packet cable voice and e-router applications, including emerging RDK-B software for broadband modem solutions

Broadcom is offering a cable modem reference design with integrated Wi-Fi that provides up to 2 Gbps speeds in the home.

"Broadcom has engineered a breakthrough technology for operators to exceed Gigabit speeds on existing cable networks while simultaneously improving operational efficiencies," said Dan Marotta, Broadcom Executive Vice President and General Manager, Broadband & Connectivity Group. "With our new cable modem SoC, service providers can immediately begin to unlock the value of DOCSIS 3.1 to provide their subscribers with the best home networking experiences."
