3 Description

The AFE031 is a low-cost, integrated, powerline

communications (PLC) analog front-end (AFE) device

that is capable of capacitive- or transformer-coupled

connections to the powerline while under the control

of a DSP or microcontroller. It is ideal for driving lowimpedance

lines that require up to 1.5 A into reactive

loads. The integrated receiver is able to detect

signals down to 20 μVRMS and is capable of a wide

range of gain options to adapt to varying input signal

conditions. This monolithic integrated circuit provides

high reliability in demanding powerline

communications applications.

The AFE031 transmit power amplifier operates from a

single supply in the range of 7 V to 24 V. At

maximum output current, a wide output swing

provides a 12-VPP (IOUT = 1.5 A) capability with a

nominal 15-V supply. The analog and digital signal

processing circuitry operates from a single 3.3-V

power supply.
