GENERAL DESCRIPTION

The ADE81651 incorporates a high performance ADC and

DAC to create a very robust CPFSK power-line communications

IC complete with networking functionality. The ADE8165

master modem IC is designed to work with the ADE8155 slave

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.
