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.  
Automatic baud rate negotiation  
Dynamic routing  
Data link layer  
CRC checking  
Network key for data security  
Physical layer  
FSK modulation  
Up to 2400 bps on a 3-phase network  
Simple serial interface to host microprocessor  
Single 3.3 V supply, low power (140 mW typical)  
Package and temperature range  
40-lead 6 mm × 6 mm LFCSP  
Fully specified for −40°C to +85°C operation  
APPLICATIONS  
Power line modems for AMR/AMI systems
