Cost-effective,no-compromise performance, using innovative and future-proof architecture, prepared for first DOCSIS® 3.1 market deployments
New Delhi , August 6, 2015 – STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, today announced the STiD325 (codenamed Barcelona), its DOCSIS3.1 chipset for Broadband CPE Cable Modems, embedded Media Terminal Adapters (eMTAs), and Gateways, as well as for Video Gateways when associated to set-top-box chipsets. It is being demonstrated at Cable Labs Summer Conference, August 2-5, 2015 in Keystone, Colorado, USA.
DOCSIS3.1 has been engineered by CableLabs® tounleash the multi-gigabit data era on existing Hybrid Fiber-Coax (HFC) networks through improved spectral efficiency using OFDM[3] 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;
- 8single-carrier DOCSIS 3.0 QAM upstream channels.
ST has a long history with DOCSIS technology, having contributedto 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.
Designed for economy and performance, Barcelona features solid technical capabilities:
- Very high performance using multiple 64-bit ARM®CPUsto 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 introductionof new services;
- Backward compatibility with DOCSIS 3.0 32x8to allow a smooth, cost-effective transition toDOCSIS 3.1;
- Flexible architecture facilitating 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;
- 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 comeswith pre-integrated RDK-B software, including DOCSIS and Packet-Cable stacks.
