ST-PLC-AFE：Power-line communication, analog front-end

The ST-PLC-AFE is a power-line communication, analog front-end device capable of capacitive or transformer-coupled connections to the power line while under the control of a microcontroller or a DSP.

The line driver is able to drive low-impedance lines, requiring up to 1.65 A, into reactive loads. It can also work in differential mode for high performance, as well as single-ended mode for a low-cost bill of materials (BOM). The integrated receiver is able to detect signals down to 20 μVrms. The system works in half-duplex mode.

The AFE is protected against over temperature and short-circuit conditions. It also provides four adjustable current limits through an internal register. Through the four-wire serial peripheral interface, or SPI, each functional block can be enabled or disabled to optimize power consumption.
