System Parameters
The following parameters specify several aspects which are important when integrating
the XC238xA into an application system.
Note: These parameters are not subject to production test but verified by design and/or
characterization.
Note: Operating Conditions apply.

1) The short-term frequency deviation refers to a timeframe of a few hours and is measured relative to the current
frequency at the beginning of the respective timeframe. This parameter is useful to determine a time span for
re-triggering a LIN synchronization.
2) This parameter is tested for the fastest and the slowest selection. The medium selections are not subject to
production test - verified by design/characterization
