About
CopperGate Communications was an Israeli fabless semiconductor company founded in 2000. It specialized in developing chipsets for multimedia home networking, utilizing existing telephone and coaxial cable infrastructure. The company was a pioneer and sole provider of the HPNA V3 standard chipsets and also developed MoCA (Multimedia over Coax Alliance) and VDSL silicon platforms. CopperGate's products supported the simultaneous provision of multiple channels like video, audio, voice, and data services, enabling reliable networking and multimedia content distribution with high data rates and Quality of Service (QoS) requirements. The company's chipsets were targeted at residential gateways, set-top boxes, network peripherals, home entertainment equipment, and MDU access systems. In 2008, CopperGate acquired the HomePlug AV business from Conexant, expanding its technology to include power line communication. CopperGate was acquired by Sigma Designs for approximately $200 million in 2009.
