BASIC CONFIGURATION
Figure 49 shows the AFE030 configured in a typical PLC analog front-end application. The schematic shows the
connections to the microprocessor and ac line. The values of the passive components in Figure 49 are suitable
for a single-phase powerline communications application in the CENELEC A band, connected to a 120-VAC or
240-VAC, 50-Hz or 60-Hz ac line.
