Preliminary Electrical Characteristics
Freescale Semiconductor

This specification applies to any time the FLL reference source or reference divider is changed, trim value is changed, DMX32 bit is
changed, DRS bit is changed, or changing from FLL disabled (BLPE, BLPI) to FLL enabled (FEI, FEE, FBE, FBI). If a
crystal/resonator is being used as the reference, this specification assumes it is already running.
3
This specification applies to any time the PLL VCO divider or reference divider is changed, or changing from PLL disabled (BLPE,
BLPI) to PLL enabled (PBE, PEE). If a crystal/resonator is being used as the reference, this specification assumes it is already
running.
4
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 VDD and VSS and variation in crystal oscillator frequency increase the CJitter percentage for a given interval.
5
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.
6
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.
7
Below Dunl minimum, the MCG will not exit lock if already in lock. Above Dunl maximum, the MCG is guaranteed to exit lock.
