ST7590 power line networking system-on-chip

description

The ST7590 device is the first complete narrowband OFDM power line communication

system-on-chip made using a multipower technology with state of the art VLSI CMOS

lithography. The ST7590 device 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.

The ST7590 device operates with a dedicated Cortex™-M3 FW library plus an embedded

FW code to implement the full PRIME protocol stack (PHY, MAC and “Convergence Layer”),

developed mainly for smart metering applications using the CENELEC A band (PRIME

Alliance).

The embedded PHY layer (PRIME PHY), hosted in a DSP engine, is PRIME compliant

(OFDM with 96 subcarriers in the 41.992 kHz to 88.867 kHz range) and implements

different n-PSK modulations: the BPSK, QPSK and 8PSK modulation with a channel quality

estimation, convolutional coding and Viterbi decoding, delivering a throughput from

21.4 kbps up to 128.6 kbps.
