GENERAL DESCRIPTION

The ADE81551 incorporates a high performance ADC and DAC

to create a very robust CPFSK power-line communications IC

complete with networking functionality. The ADE8155 slave

modem IC is designed to work with the ADE8165 master modem

IC for a complete power-line communication system.

In an advanced metering infrastructure (AMI) scenario, the

ADE8155 slave modem IC is used to connect the energy meter

to the power line. Then the ADE8165 master PLC modem is

used near the transformer to communicate with multiple meters

on one phase. The power-line communication is independent

on each phase; therefore, three ADE8165 master PLC modem

ICs are used in a PLC module within the concentrator to read

meters on all three phases.

A UART communication interface is supported.
