Systems using this ASIC support both mono-phase and multi-phase PLC injection. Mono-phase injection is achieved by means of a single ATPL220A device, whereas several ATPL220A can be combined to achieve multi-phase injection based on Atmel MIMO technology. The combination of multi-phase injection and Atmel MIMO technology increases PRIME Base Nodes performance, resulting in outstanding robustness and network coverage. ATPL220A has been conceived to be easily managed by an external microcontroller by means of an SPI interface. The external microcontroller implements Base Node upper layers (as specified in PRIME standard) while ATPL220A carries out PHY layer functionalities. Line coupling front end design is extremely simplified, resulting in a very low cost bill of materials. 2 Atmel ATPL220A Datasheet 43008A-ATPL-05/12
