DOCSIS 3.1 has been engineered by CableLabs® to allow multi-gigabit data transport on existing Hybrid Fiber-Coax (HFC) networks through improved spectral efficiency using OFDM multi-carrier modulation combined with low-density parity-check-based Forward Error Correction.

The chipset is fully compliant with the DOCSIS 3.1 specification, featuring two 196 MHz OFDM downstream channels; 32 single-carrier DOCSIS 3.0 QAM downstream channels; two 96 MHz OFDM-A upstream channels; an 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. Codenamed Barcelona, the high performance chipset relies on multiple 64-bit ARM® CPUs to deliver over 10K DMIPS, with line-rate networking support on every port, and hardware acceleration for routing and switching. It will allow Multiple System Operators (MSOs) to build future-proof CPE platforms with plenty of headroom to support the field introduction of new services. Its flexible architecture facilitates independent software development and software upgrades with minimal coupling between stacks, as well as the introduction of new features like home surveillance and home automation; support of various Wi-Fi configurations;

The chipset is built on 28nm FD-SOI silicon technology, providing outstanding power efficiency at all operating levels, including fan-less designs, along with highly-efficient RF and analog integration. Currently sampling to lead customers, Barcelona comes with pre-integrated RDK-B software, including DOCSIS and Packet-Cable stacks.
