GENERAL DESCRIPTION

The

includes a physical layer (PHY), data link layer (DLL), and net-

working layer (NL). The

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

meter over the on-chip UART. The

is designed to work with the

complete power line communication system.

In an advanced metering infrastructure (AMI) system, the

ADE8157

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

modem.
