To achieve specified RF-ADC performance, certain calibration mode must be set correctly according to the signal location. The available calibration modes are listed as follows:

  • Mode 1, optimized for the input signal locates from 0.4 * Fs to Fs/2
  • Mode 2, optimized for the input signal locates from 0 to 0.4 * Fs

The above location refers to the input signals in the first Nyquist band after aliasing.

AutoCal Mode
This mode is available in Gen 3/DFE. The AutoCal mode removes the manual selection of Mode 1 and Mode 2 calibrations and optimizes the RF-ADC performance regardless of signal locations.
