[原创] ST STCOMET智能电表和动力线通信(PLC)开发方案

ST公司的STCOMET是集成了智能电表和动力线通信(PLC)的系统级芯片(SoC),包括PLC调制解调器(Modem),高性能应用核和计量功能,支持PRIME,G1,G3,IEEE 1901.2,METERS AND MORE®和其它窄带PLC协议指标,计量子系统适用于EN 50470-1,EN 50470-3,IEC 62053-21, IEC62053-22和IEC 62053-23.主要用在智能电表,智能电网和物联网 (IoT).本文介绍了STCOMET主要特性,框图,架构图和时钟树,参考应用电路图以及开发套件EVLKSTCOMET10-1主要特性,功能框图,和火线连接图以及主板,LCD和电源电路图,材料清单和PCB设计图.

The STCOMET is a device that integrates a power line communication (PLC) modem,a high-performance application core and metrology functions.

The PLC modem architecture has been designed to target EN50065, FCC, ARIB compliantPLC applications. Together with the application core, it enables the STCOMET to supportthe PRIME, G1, G3, IEEE 1901.2, METERS AND MORE® and other narrow band PLCprotocol specifications.

The metrology sub-system is suitable for EN 50470-1, EN 50470-3, IEC 62053-21, IEC 62053-22 and IEC 62053-23 compliant class1, class0.5 and class0.2 AC meteringapplications.

STCOMET主要特性:

 Integrated differential PLC analog front-end
– PGA with automatic gain control and ADC
– Current DAC with transmission predriver
– Digital transmission level control
– Zero crossing comparator..
