GENERAL DESCRIPTION
The ADE8155 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.
