The PLC reception circuit used in PL460-EK (see Figure 3-12) is the reference design for the reception stage, and it is composed
of:
Single-pole low pass filter, R21 and
C11
Automatic Gain Control (AGC) circuit.
A resistor, R24, is used to attenuate the incoming PLC signal in case its amplitude
is high enough to exceed the input dynamic range of the embedded ADC
