ST7570 S-FSK power line networking system-on-chip

description

The ST7570 is a powerful power line networking system-on-chip, combining a high-

performing PHY processor core and a protocol controller core with a fully integrated analog

front end (AFE) and line driver, for a scalable future-proof, cost effective single chip narrow-

band power line communication solution based on IEC61334-5-1 S-FSK technology

(References 5).

The ST7570 comes with a dedicated FW implementing full PHY and MAC protocol layers

and services compliant with the open standard IEC 61334-5-1, mainly developed for smart

metering applications in EN50065-1 A band, but also usable for other command and control

applications and remote load management in B band (References 4).

The on-chip analog front end, featuring analog-to-digital and digital-to-analog conversion

and automatic gain control, plus the integrated power amplifier delivering up to 1 A rms

output current, makes the ST7570 the first complete system-on-chip for power line

communication.

The line coupling network design is also simplified, leading to a very low cost BOM. Safe

performance operations are guaranteed while keeping power consumption and distortion

levels very low, therefore making ST7570 an ideal platform for the most stringent application

requirements and regulatory standard compliance.
