3 Description
The AFE030 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 digital signal processor (DSP) or microcontroller.
It is ideal for driving low-impedance lines that require
up to 1 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 AFE030 transmit power amplifier operates from a
single supply in the range of 7 V to 26 V. At
maximum output current, a wide output swing
provides a 12-VPP (IOUT = 1 A) capability with a
nominal 15-V supply. The analog and digital signal
processing circuitry operates from a single 3.3-V
power supply.
