12.6.18.2 Digital Filter Performance
The performance of the digital filter is best described in the time domain rather than the frequency domain.
If the signal on the SLCRX signal transitions, then there will be a delay before that transition appears at
the filtered Rx data output signal. This delay will be between 15 and 16 clock periods, depending on where
the transition occurs with respect to the sampling points. This ‘filter delay’ is not an issue for SLIC
operation, as there is no need for message arbitration.
The effect of random noise on the SLCRX signal depends on the characteristics of the noise itself. Narrow
noise pulses on the SLCRX signal will be completely ignored if they are shorter than the filter delay. This
provides a degree of low-pass filtering.
and the consequential effect on the filter delay. This filter delay value indicates that for a particular setup,
only pulses of which are greater than the filter delay will pass the filter.
For example, if the frequency of the SLIC clock (f
clock is 313 ns. With a receive filter prescaler setting of division by 3, the resulting maximum filter delay
in the absence of noise will be 15.00 μs. By simply changing the prescaler of the receive filter, the user can
then select alternatively 5 μs, 10 μs, or 20 μs as a minimum filter delay according to the systems
requirements.
If noise occurs during a symbol transition, the detection of that transition may be delayed by an amount
equal to the length of the noise burst. This is just a reflection of the uncertainty of where the transition is
truly occurring within the noise.
Freescale Semiconductor
The user must always account for the worst case bit timing of their LIN bus
when configuring the digital receive filter, especially if running at faster
speeds. Ground offset and other physical layer conditions can cause
shortening of bits as seen at the digital receive pin, for example. If these
shortened bit lengths are less than the filter delay, the bits will be interpreted
by the filter as noise and will be blocked, even though the nominal bit timing
might be greater than the filter delay.
