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 low-
impedance 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.
