ST unveils DOCSIS 3.1 chipset made using 28nm FD-SOI

STMicroelectronics, being a long supporter of DOCSIS technology and also leading vendor of STB/cable media access/control semiconductor technology has announced the STiD325 (codenamed Barcelona), its DOCSIS1 3.1 chipset for Broadband CPE2 Cable Modems, embedded Media Terminal Adapters (eMTAs), and Gateways, and also for Video Gateways when associated to set-top-box chipsets. These chips are demonstrated at CableLabs Summer Conference, August 2-5, 2015 in Keystone, Colorado, USA. DOCSIS 3.1 by CableLabs enables multi-gigabit data on existing Hybrid Fiber-Coax (HFC) networks through improved spectral efficiency using OFDM3 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 QAM4 downstream channels; Two 96 MHz OFDM-A upstream channels;...
