In an advanced metering infrastructure (AMI) scenario, the ADE8167 IC provides the essential functions for a master modem; maintaining the network configuration and relaying messages between the utility back office and the slave modems associated with the energy meters. The ADE8167 is a complete digital baseband processor IC which includes physical layer, data link layer and networking layer functionality. The ADE8167 includes a receive path 12-bit ADC and a transmit path digital demodulator to reduce the external analog front end component count. The ADE8167 UART communicates directly with a host microprocessor. The ADE8167 master modem IC is designed to work with the ADE8157 slave modem IC for a complete power-line communication system. Applications Power line modems for AMR/AMI systems
