Description
The ST7570 is a powerful power line networking
system-on-chip. It combines a high-performance
PHY processor core and a protocol controller core
with a fully integrated analog front end (AFE) and
line driver.
The ST7570 features allow the most cost-
effective, single-chip power line communication
solution based on IEC61334-5-1 S-FSK standard.
