CALIBRATION MODES
The AFE031 can be configured for three different calibration modes: Tx Calibration, Rx Calibration, and Tx PGA
Calibration. Calibration values can be determined during the calibration process and stored in system memory. A
one-time calibration can be performed the first time that the system powers on; this calibration remains valid over
the full temperature range and operating life of the AFE031, independent of the number of power-on/power-off
cycles, as long as the calibration factors remain in the system memory. Calibration mode is accessed through the
Control1 Register. Note that calibration is not required.
Tx Calibration Mode
The Tx PGA + Tx Filter ac gain can be calibrated in Tx Calibration Mode. Figure 46 shows the signal path during
Tx Calibration mode.
Figure 46. Tx Calibration Mode Configuration
Rx Calibration Mode
The Tx PGA + Rx PGA1 + Rx Filter + Rx PGA2 ac gain can be calibrated in Rx Calibration mode. Figure 47
shows the signal path during Rx Calibration mode.
