... In the calibrated mode the phase shift between input and output signal is no longer determined by the ratio between digital noise constant and signal amplitude. Therefore a sudden change in the phase shift may occur during the transition from uncalibrated to calibrated mode.

... Unlike the TLE4942 the first output pulse might occur before the first zero-crossing of the magnetic input signal. Therefore the maximum number of edges until the calibrated mode is active is increased by one for TLE4942-2. However, referring to the input signal the delay between startup of the signal and first calibrated output signal is identical with TLE 4942 ...

... Rows 12..15: behaviour at initial phases of 0°.. 90° Remark: the additional PGA switching can only occur once per row. Therefore also the additional phase shift marked "150°..200° (cal/uncal)" will only occur once per row.
