Appendix A Electrical Characteristics
3 _{Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fBUS.}
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_DD and V_SS and variation in crystal oscillator frequency increase the C_Jitter percentage for a given
interval.
4 _{625 ns represents 5 time quanta for CAN applications, under worst case conditions of 8MHz CAN bus clock, 1Mbps 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.
5 _{Below Dlock minimum, the MCG is guaranteed to enter lock. Above Dlock maximum, the MCG will not enter lock. But if the MCG}
is already in lock, then the MCG may stay in lock.
6 _{Below Dunl minimum, the MCG will not exit lock if already in lock. Above Dunl maximum, the MCG is guaranteed to exit lock.}
