Initial Edge Detection. The device self-calibrates using the
initial teeth sensed, and then enters Running mode. This results
in reduced accuracy for a brief period (less than four teeth),
however, it allows the device to optimize for continuous update
yielding adaptive sensing during Running mode. As shown in
figure 5, the first three high peak signals are used to calibrate
AGC. However, there is a slight variance in the duration of
initialization, depending on what target feature is nearest the
package when power-on occurs.
Figure 5. Power-on initial edge detection. This figure demonstrates four typical power-on scenarios. All of these examples assume that the target is
moving relative to the package in the direction indicated. The length of time required to overcome Start Mode Hysteresis, as well as the combined effect
of whether it is overcome in a positive or negative direction plus whether the next edge is in that same or opposite polarity, affect the point in time when
AGC calibration begins. Three high peaks are always required for AGC calibration.
