Sigma Designs Awarded HomeGrid Forum's G.hn Certification

MILPITAS, CA--(Marketwired - Jun 2, 2013) - Sigma Designs® ( NASDAQ : SIGM ), a leading provider of System-on-Chip (SoC) solutions for home entertainment, control, connectivity and converging multimedia delivery was awarded the HomeGrid Forum's full compliance certification for their ITU-T G.hn chipset.

Consumers today face a mix of non-interoperable home networking technologies across the various wired media in the home. G.hn offers a single open international standard for establishing high bandwidth communications across all existing wires. With Sigma Designs' CG5200 G.hn chipset, every power outlet, coaxial outlet and phone jack in the home becomes a network connectivity point on the same network, providing consumers with convenience and flexibility. This enables VoIP, HD IPTV, gaming and multi-room DVR traffic to be delivered seamlessly over any wired medium in the home. With HomeGrid Forum's certification of Sigma Designs' CG5200 G.hn chipset, customers can develop systems with high performance, flexibility and reliability for streaming multimedia content across multiple platforms in next-generation networked homes, taking this technology into global markets.

Device manufacturing customers such as Comtrend, ZTE, T & W and ZyXEL have already announced they have selected Sigma Designs' CG5200 series chipsets for their powerline adapters. These adapters utilize the highest performance over powerline offered by the G.hn technology and full self-install for home networks for streaming high-definition videos, music and other rich digital multimedia content.

"HomeGrid Forum certification for our CG5200 G.hn chipset means that our customers can be confident they are developing systems with the highest performance, flexibility and reliability for streaming multimedia content across multiple platforms in next-generation networked homes, taking this mature technology further into global markets," said Gabi Hilevitz, Sigma Designs' vice president and general manager Home Connectivity business unit.

Welcoming Sigma Design's silicon success, John Egan, President of the HomeGrid Forum, said: "The addition of a new source of certified silicon is an important step for the market, providing variety and choice for service providers and system companies, delivering on HomeGrid's multi-source promises. We applaud Sigma Designs' dedication and commitment to G.hn which culminated in this success and their achieving recognition for their certified G.hn silicon."
