The ADE8157 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) driver. The ADE8157 can communicate directly with an energy meter over the on-chip UART. The ADE8157 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) 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 ADE8165 IC provides the foundation for a master PLC modem.
