Tx PGA Calibration Mode
The Tx PGA ac gain can be calibrated in Tx PGA Calibration mode. Figure 48 shows the signal path during Tx
PGA Calibration mode.

BASIC CONFIGURATION
Figure 49 shows the AFE031 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.
