Broadcom Announces Industry’s First Multi-Gigabit Set-Top Box Design

  • Combines Five Gbps DOCSIS 3.1 Broadband Speeds, Ultra HD Video and Gigabit Wi-Fi into a Single Platform

COLOGNE, Germany — ANGA COM — Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced the world’s first DOCSIS 3.1 cable set-top box (STB) reference design. Broadcom’s BCM93390VMS52 provides global cable system operators and original equipment manufacturers (OEMs) with a powerful all-in-one cable subscriber experience that combines data delivery at speeds of up to five Gigabits per second (Gbps), support for 4K/Ultra HD video decoding and multi-Gigabit Wi-Fi home networking.

“Competition among service providers is driving an increase in Gigabit Internet speeds and 4K IP video around the world. Broadcom is bringing to market an extraordinary set-top box reference design that gives service providers a platform to enable the best connectivity performance available today,” said John H. Gleiter, Broadcom Vice President of Marketing, Broadband & Connectivity Group. “With Broadcom’s latest platform, service providers and OEMs can immediately begin to leverage the value of DOCSIS 3.1 to provide their customers with market-leading Gigabit broadband data speeds, the highest-speed dual concurrent 4×4 Wi-Fi for streaming Internet content to wireless devices and Ultra HD cable TV experiences.”

Engineered to support the new era in Gigabit data and improve the spectral efficiencies of current networks, the DOCSIS 3.1 specification enables higher-order modulations in existing hybrid fiber-coaxial (HFC) networks without changes to the existing cable plant. By combining low-density parity check-based Forward Error Correction (FEC) and Orthogonal Frequency Division Multiplexing (OFDM) technology, DOCSIS 3.1 allows operators to more efficiently pack more data into the existing spectrum.
