Data in “Typical” column is at 3.3V, +25°C unless otherwise stated. Parameters are for design guidance
only and are not tested.
This jitter specification is based on clock cycle-by-clock cycle measurements. To get the effective jitter for
individual time bases or communication clocks used by the application, use the following formula:
For example, if F
Change of LPRC frequency as V
CLK
Frequency calibrated at 25°C and 3.3V. TUN bits can be used to compensate for temperature drift.
