3.3.5.2 PLC Filtering Circuit

The in-band flat response filtering stage reduces spurious emission to the limits set by the corresponding regulation and blocks potential interferences from other transmission channels without distorting the injected signal.

The filtering stage used in PL360G55CF-EK, see Figure 3-11, has three aims:

Band-pass filtering of high frequency components of the square waveform generated by the transmission stage
Adapt Input/Output impedance for optimal reception/transmission. This is controlled by TXRX0 and TXRX1 signal
A band-pass filtering for received signals
