Typical values are based on characterization data at V
This is the shortest pulse that is guaranteed to be recognized as a reset pin request. Shorter pulses are not guaranteed to
override reset requests from internal sources.
This is the minimum pulse width guaranteed to pass through the pin synchronization circuitry. Shorter pulses may or may not
be recognized. In stop mode, the synchronizer is bypassed so shorter pulses can be recognized in that case.
Timing is shown with respect to 20% V
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the FLL circuitry via V
a given interval.
Jitter measurements are based upon a 48 MHz clock frequency.
625 ns represents 5 time quanta for CAN applications, under worst case conditions of 8 MHz CAN bus clock, 1 Mbps CAN
bus speed, and 8 time quanta per bit for bit time settings. 5 time quanta is the minimum time between a synchronization edge
and the sample point of a bit using 8 time quanta per bit.
