DOCSIS 3.1 has been engineered by CableLabs to enable the multi-gigabit data era on existing Hybrid Fibre-Coax (HFC) networks through improved spectral efficiency using OFDM multi-carrier modulation combined with low-density parity-check-based Forward Error Correction.
“Prepared to be among the first commercial DOCSIS 3.1 deployments, our innovative platform architecture supports our ambition to make Barcelona a reference in the cable industry,” said Philippe Notton, Group Vice President and General Manager of STMicroelectronics’ Consumer Product Division. “As a standalone for multi-gigabit cable gateways or combined with our Monaco SoC for an UltraHD media gateway, ST can offer complete solutions for fast design.”
Barcelona is fully compliant with the DOCSIS 3.1 specification, including:
Two 196 MHz OFDM downstream channels;
32 single-carrier DOCSIS 3.0 QAM downstream channels;
Two 96 MHz OFDM-A upstream channels;
8 single-carrier DOCSIS 3.0 QAM upstream channels.
ST has contributed to the standards and participated in all Acceptance Test Plan development committees and Interoperability tests. Demonstrating the value of that effort, the Barcelona early platform operated successfully in the world’s first end-to-end DOCSIS 3.1 field test conducted earlier this year.
· Very high performance using multiple 64-bit ARM CPUs to deliver >10K DMIPS, line-rate networking support on every port, and hardware acceleration for routing and switching, allowing Multiple System Operators (MSOs) to build future-proof CPE platforms with plenty of headroom to support the field introduction of new services;
· Backward compatibility with DOCSIS 3.0 32x8 to allow a smooth, cost-effective transition to DOCSIS 3.1;
· Flexible architecture facilitating independent software development and software upgrades with minimal coupling between stacks, as well as the introduction of new features such as home surveillance and home automation; support of various Wi-Fi configurations;
· 28 nm FD-SOI silicon technology, providing power efficiency at all operating levels, including fan-less designs, along with highly-efficient RF and analogue integration.
Currently sampling to lead customers, Barcelona comes with pre-integrated RDK-B software, including DOCSIS and Packet-Cable stacks.
