A versatile low-power power line FSK transceiver

Abstract

A versatile low-power half-duplex FSK transceiver for power line communication network applications is presented. The proposed power-line modem (PLM) satisfies the requirement of several protocols for both power-line communications and home automation applications. The device operation is fully controlled and programmed through an internal 24 bit register. It operates from a single 9 V supply (5 V is possible if no power delivery is required). During transmission, the PLM is able to deliver 1 W on 16 /spl Omega/, while during reception if dissipates only 3.5 mA. The PLM is realized in a 0.6 /spl mu/m BCD technology.
