GENERAL DESCRIPTION

In an advanced metering infrastructure (AMI) scenario, the

ADE81671. 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 that

includes physical layer, data link layer, and networking layer

functionality. The ADE8167 includes a receive path 12-bit

analog-to-digital converter (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 communications system.
