1) Magnetic amplitude values, sine magnetic field, Limits refer to the 50% critera. 50% of pulses are missing or
2) The sensor requires up to
3) One magnetic edge is defined as a montonic signal change of more than 3.3 mT
4) Direction signal is given already during uncalibrated mode. Assembly Bit information is only provided in
5) High frequency behavior not subject to production test - verified by design/characterization. Frequency above
6) During fast offset alterations, due to the calibration algorithm, exceeding the specified duty cycle is permitted
7) Not subject to production test- verified by design/characterization
wrong. Valid in calibrated mode only.

2500 Hz may have influence on jitter performance and magnetic thresholds. DR-R pulse length will be cut off
above app. 3.3 kHz Therefore direction detection may not be possible anymore at high frequency.
