Control LED lighting over the mains with HomePlug Green PHY
The Californian start-up Greenvity is claiming a first – a HomePlug Green PHY has been implemented in a chip for over-mains control of LED lighting.
“HomePlug AV is used in set-top boxes in Europe and is starting in the US,” said Greenvity CEO Hung Nguyen. “Any lighting system needs to be interoperable with set-top boxes. HomePlug Green PHY co-exists and inter-operates with HomePlug AV.”
The GV7013 can be used at either ends of a mains-based control link, bridging SPI, UART or I2C onto mains wiring from the controller, and recovering SPI, UART, I2C. It also generates 3xPWM waveforms for colour tuning, at the controlled end.
The firm says the system will also work with IEEE P1901-based products such as home gateways and routers
