ST7580

ST7580 is a flexible power line networking system-on-chip combining a high-performing PHY processor core and a protocol controller with a fully integrated analogue front-end (AFE) and line driver for a scalable future-proof, cost-effective, single-chip, narrow-band power line communication solution. It is used in applications such as smart metering applications, street lighting control, and command and control networking. The on-chip analogue front-end featuring analogue to digital and digital to analogue conversion, automatic gain control, plus the integrated power amplifier delivering upto 1A RMS output current makes the device a unique system-on-chip for power line communication. Line coupling network design is also simplified, leading to a very low-cost BOM.
