TLE5011
Specification
DATA Write Time ( t_DATW )
During this time, the TLE5011 changes the data line, so the data are invalid. The DATA Write Time values are
defined without a pull-up resistor.
Pull-up Time Value ( t_PU )
The value in Table 11 “SSC Timing Specification” on Page 23 is estimated at 60 ns.

Note: Timing must be calculated according to Table 10 “CLK Timing Specification” on Page 21

Note: The read window includes the sampling of the data bit. For SSC_FILT = 1, the 2-of-3 selection is already
considered. Only the two last data values need to be equal. For SSC_FILT = 0, only one sample point is
selected.
