ST7590 PRIME compliant power line networking SoC design guide

Riccardo Fiorelli

Introduction

The ST7590 reference design has been realized as a useful tool that exploits the

performance capability of the ST7590 power line networking system-on-chip.

With this reference design, it is possible to evaluate, directly on the power line, the

transmitting and receiving performance of a power line communication node based on the

ST7590 device.

The line coupling interface is designed to allow the ST7590 device to transmit and receive

on the AC mains line using the PRIME OFDM signal within the European CENELEC

EN50065-1 standard A band, specified for “Automatic Meter Reading” (AMR) applications

(see Part 1 of Section 14: Normative references on page 63).

An STM32™ microcontroller has been included in the reference design to make it very

flexible and suitable for use as a standalone smart PLC node.

As it can be seen from Figure 1, a special effort has been done to make the reference

design compact and optimized, while including all the features enabling the ST7590 device

to perform at its best.
