FEATURES Narrow-band power-line communications IC Integrates PHY through networking layer Simple host interface Application layer Supports DL/T 645-1997 or -2007 China-specific protocol as well as passthrough option Networking layer Master/slave architecture Designed to work with ADE8165 master PLC modem ICs, which support Dynamic routing Automatic discovery of authenticated devices Logical address management Data link layer Automatic baud rate negotiation Up to 63-byte packet support Physical layer CPFSK modulation Choice of two frequency bands Carrier frequencies: 105.5 kHz and 118.7 kHz Carrier frequencies: 74.9 kHz and 84.2 kHz Up to 800 bps on a 1-phase network and 2400 bps on a 3-phase network Zero-crossing synchronized receive/transmit 6-byte physical address for logical address assignment Communication interface UART Option to use DL/T 645-1997 or -2007 China-specific application layer interface Package and temperature range 40-lead 6 mm × 6 mm LFCSP Fully specified for −40°C to +85°C operation GENERAL DESCRIPTION The ADE81551 incorporates a high performance ADC and DAC to create a very robust CPFSK power-line communications IC complete with networking functionality. The ADE8155 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) scenario, the ADE8155 slave modem IC is used to connect the energy meter to the power line. Then the ADE8165 master PLC modem is used near the transformer to communicate with multiple meters on one phase. The power-line communication is independent on each phase; therefore, three ADE8165 master PLC modem ICs are used in a PLC module within the concentrator to read meters on all three phases. A UART communication interface is supported. For more information on the ADE8155, contact your local sales office at Analog Devices, Inc. 1 US patents pending.
