ST7540     FSK stripped down power line transceiver

STMicroelectronics’ narrowband Power Line Transceivers (PLT) provide reliable communication over existing power lines with limited data throughput required by main remote control applications like Automatic Meter Reading (AMR) and Management (AMM), street lighting control, loads management and home and building automation.
The very favorable cost/performance ratio makes ST’s transceivers a unique communication alternative or extension of more conventional dedicated wireline and
wireless systems.
This new ST7540 Power Line Transceiver is the most compact and cost effective solution from ST.
