Features
- 6 independent galvanically isolated frequency outputs
- Support of conventional wheelspeed sensors as well as wheelspeed sensors with serial data protocol, e.g. Continental OH42x and OH44x
- Possibility to simulate missing teeth
- Configurable jitter for each individual tooth
- Support of the currents needed by the ECU, no external adaptation circuits necessary
- Usable as current source and current sink
- Possible currents: +/-7, 14, 21mA and 28 mA
- Accuracy and range of values: 40 bits
- Jitter (peak to peak): 7.5ns
- Galvanic isolation for each channel to each other and to system supply
- 2 different frequency update modes:
- Immediate frequency adaptation
- Synchronized frequency adaptation - 3 different pulse width modes:
- Pulse-duty factor
- Fixed high level duration
- Fixed low level duration
