Description
ST7590 is the first complete Narrowband OFDM
power line communication system-on-chip made
using a multi-power technology with state of the
art VLSI CMOS lithography. The ST7590 is based
on dual core architecture to assure outstanding
communication performance with a very high level
of flexibility and programmability for either open
standard or fully customized implementations.
