Description

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.
