Input capacitance typical
168 pF
SAE J2716 SENT
(Single Edge Nibble Transmission)
sensor signal input

For sensor ground use SGND_2
Filter limit frequency 140.8 kHz
Check API manual for SENT signal
evaluation.
Digital input
Low Level < 1.6 V
High Level > 3 V
(max. 5 V)
10, 30, 12, 13, 70, 61 IN_26 to IN_31
Only in DSM configuration:
Pull down resistor
196 Ω to GND
Active frequency sensor
input or analog input con-
figuration:
Pull-down resistor
11.2 kΩ to GND
Frequency input for Bosch Rexroth
DSM speed sensors
The DSM signal includes frequency,
direction and diagnosis information
Low Level < 8.4 mA
High Level > 11.2 mA
Measurable range 0 .. 10 kHz
(relates to 5 kHz tooth frequency
due to duplication of frequency by
DSM)
DSM standstill detection can be
used
Filter limit frequency 26.2 kHz
Frequency input for active speed sensors
that switch to high level
Low Level < 1.7 V
High Level > 2 V
Measurable range up to 20 kHz
▶ minimal pulse length 25 µs
▶ the lower frequency limit depends on the
period used in software for the fre-
quency acquisition
Filter limit frequency 26.2 kHz
The phase between two frequency inputs
can be used to acquire the direction
Phase 1: IN_26 / IN_27
Phase 2: IN_28 / IN_29
Phase 3: IN_30 / IN_31
Analog voltage input
Measuring range nominal 0 to 32 V
Resolution 12 bits
Resolution 8.78 mV / bit
Accuracy ± 6 % at 32 V
Filter limit frequency 700 Hz
Digital input
Switching threshold configurable in soft-
ware (max. 32 V)
63, 64 IN_32 to IN_33
Pull-down resistor
40 kΩ to GND and
Pull-up resistor
6.8 kΩ to 5 V
Open pin voltage 3.6 V
Frequency input for active speed
sensors that switch to low level
Low Level < 1.3 V
High Level > 3.5 V
Filter limit frequency 28.5 kHz
Measurable range up to 20 kHz
▶ minimal pulse length 25 µs
▶ the lower frequency limit depends
on the period used in software for
the frequency acquisition
The phase between these two
frequency inputs can be used to
acquire the direction
Phase 4: IN_32 / IN_33
Analog voltage input
Measuring range nominal 0 to 32 V
Resolution 12 bits
Resolution 8.78 mV / bit
Accuracy ± 6 % at 32 V
Filter limit frequency 700 Hz
Digital input
Switching threshold configurable in soft-
ware (max. 32 V)
