In a majority of homes, electrical power is divided into multiple phases, with appliances distributed across these phases. When using Cypress’ PLC solution, a phase coupler is required for the Powerline packets from nodes in one phase to pass through to nodes on the other phase. This application note describes the use of Cypress’ CyFi technology to build a phase coupler that bridges the two phases using a wireless link. It describes the hardware interface between the Artaflex CyFi module and CY8CPLC20 device and the firmware code for the PLC device that accomplishes this application. The code example for the CY8CPLC20 device is attached.
