STMicroelectronics is getting serious about the cable business.
The chipmaker announced Monday that it will preview a DOCSIS 3.1-based platform at this week’s International CES in Las Vegas, showing off a “live demonstration” of a next-gen cable broadband platform that’s built to support speeds of up to 10 Gbps downstream and 2 Gbps upstream. STMicro said the D3.1 demo will be run over standard coax with an unnamed third-party cable modem termination system (CMTS) over a single 96 MHz-wide channel using OFDM (Orthogonal Frequency Division Multiplexing) modulation with sub-carrier modulated in 4096QAM, and upstream communication via a 80 MHz-wide channel modulated in 1024QAM.
STMicro said it will also show the integration of a RDK-B stack, an emerging version of the Reference Design Kit that will support cable broadband gateways. The original version of the RDK, a preintegrated software stack being managed by Comcast, Time Warner Cable and Liberty Global, was designed for hybrid QAM/IP and IP-only video devices.
CableLabs conducted its first DOCSIS 3.1 interop last month, and has a second one slated to take place January 19-23, 2015. CableLabs is expected to start official DOCSIS 3.1 certification and qualification testing as early as the second quarter of this year.
"Service providers will want to introduce DOCSIS 3.1 equipment quickly and seamlessly into their networks and our ‘First-Time-Right’ methodology and successful demonstration proves that we are on course to deliver the mature and certified solutions the industry needs to roll out compliant cable gateways to subscribers throughout North America and Europe when they are ready," said Philippe Notton, STMicro group VP & GM, and general manager of the company’s consumer product division, in a statement.
