Application note
ST7570 S-FSK power line networking system-on-chip
design guide for AMR
Introduction
The ST7570 demonstration board has been realized as a useful tool which exploits the
performance capability of the ST7570 S-FSK power line networking system-on-chip
(References 1).
With this demonstration board, it is possible to evaluate the ST7570 features and its
transmitting and receiving performance directly on the power line.
The coupling interface is designed to allow the ST7570 device to transmit and receive on the
mains using a spread-spectrum FSK signal with 63.3 and 74 kHz tone frequencies, within
the European CENELEC EN50065-1 standard A-band, specified for automatic meter
reading (References 4).

Note:
As can be seen from Figure 1, special effort has been made to make the demonstration
board as compact as possible, while including all the features which enable the ST7570 to
perform at its best.
The information provided in this application note refers to the EVALST7570-1 demonstration
board.
