GENERAL DESCRIPTION
The ADE81571 is a complete digital baseband processor IC that
includes a physical layer (PHY), data link layer (DLL), and networking layer (NL). The ADE8157 includes a high performance
receive path analog-to-digital converter (ADC) to reduce the
external component count. An on-chip digital modulator creates
the transmit signal for an external field effect transistor (FET)
dr iver. The ADE8157 can communicate directly with an energy
meter over the on-chi p UAR T. The ADE8157 slave modem IC
is designed to work with the ADE8167 master modem IC for a
complete power line communication system.
In an advanced metering infrastructure (AMI) system, the
ADE8157 IC provides the essential functions of a slave modem,
which enables energy meters to communicate over the power
line. Each slave modem operates as a node in a mesh network.
The mesh network is under the control of a single master modem.
The ADE8167 IC provides the foundation for a master PLC
modem.
