Power Line Communications
Master Modem IC
Data Sheet
ADE8167
FEATURES
GENERAL DESCRIPTION
Narrow-band power line communications IC
Integrates physical, data link and networking layers
Application layer
Supports DL/T 645-1997 or DL/T 645-2007 data protocol
(specific to China), as well as a pass through option
Networking layer
In an advanced metering infrastructure (AMI) scenario, the
ADE81671. IC provides the essential functions for a master
modem; maintaining the network configuration and relaying
messages between the utility back office and the slave modems
associated with the energy meters.
The ADE8167 is a complete digital baseband processor IC that
includes physical layer, data link layer, and networking layer
functionality. The ADE8167 includes a receive path 12-bit
analog-to-digital converter (ADC) and a transmit path digital
demodulator to reduce the external analog front-end component
count. The ADE8167 UART communicates directly with a host
microprocessor. The ADE8167 master modem IC is designed to
work with the ADE8157 slave modem IC for a complete power
line communications system.
