3.3.5.4 PLC Reception Circuit

The PLC reception circuit used in PL360G55CF-EK, see Figure 3-11, is the reference design for the reception stage and it is composed of:

Single-pole low pass filter, R140 and C114
Automatic Gain Control (AGC) circuit. A resistor, R143, 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
A resistor, R141, for impedance matching
DC decoupling capacitor, C113
