GENERAL DESCRIPTION
The ADE8165
1
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.
