The STCOM is a device that integrates a power line communication (PLC) modem and a high-performance application core.
The PLC modem architecture has been designed to target the EN50065, FCC, ARIB compliant PLC applications. Together with the application core, it enables the STCOM to support the ITU-T G.9001, ITU-T G.9903 (G3-PLC®), ITU-T G.9904 (PRIME), IEEE 1901.2, IEC 61334-5-1 (G1), CLC/TS 50568 (METERS AND MORE®) and other narrow band PLC protocol specifications.
The STCOM basic block diagram is shown in Figure 1.Key Features
