The optional bandpass filter on the RX path that is shown in Figure 4-4 is used to help suppress any frequencies that are outside the modulated carrier frequency of the data signal. Since the HV interface does some initial filtering this is not necessary, but it helpful in further cleaning up the signal. The BOOSTXL-AFE031-DF1 also provide a good RX path architecture which can be utilized here. This is shown in Figure 4-4

With a basic understanding of the signal path for the system – it is time to look at the system from top level including powering and operating the system.
