    1 Nominal crystal and external reference values are worst-case not more than 1%. The device operates correctly if the frequency
    remains within ± 5% of the specification limit. This tolerance range allows for a slight frequency drift of the crystals over time.
    The designer must thoroughly understand the drift margin of the source clock.
    2 All internal registers retain data at 0 Hz.
    3 Up to the maximum frequency rating of the device (refer to Table 1).
    4 Loss of reference frequency is defined as the reference frequency detected internally, which transitions the PLL into self-clocked
    mode.
    5 The PLL operates at self-clocked mode (SCM) frequency when the reference frequency falls below f
    LOR. SCM frequency is
    measured on the CLKOUT ball with the divider set to divide-by-two of the system clock.
    NOTE: In SCM, the MFD and PREDIV have no effect and the RFD is bypassed.
    6 Use the EXTAL input high voltage parameter when using the FlexCAN oscillator in crystal mode (no quartz crystals or
    resonators). (Vextal – Vxtal) must be 400 mV for the oscillator’s comparator to produce the output clock.
    7 Use the EXTAL input low voltage parameter when using the FlexCAN oscillator in crystal mode (no quartz crystals or
    resonators). (Vxtal –Vextal) must be 400 mV for the oscillator’s comparator to produce the output clock.
    8 I
    xtal is the oscillator bias current out of the XTAL pin with both EXTAL and XTAL pins grounded.
    9 C
    PCB_EXTAL and CPCB_XTAL are the measured PCB stray capacitances on EXTAL and XTAL, respectively.
    10 This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the
    synthesizer control register (SYNCR). From power up with crystal oscillator reference, the lock time also includes the crystal
    startup time.
    11 PLL is operating in 1:1 PLL mode.
    12 V
    DDE = 3.0–3.6 V.
    13 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
    sys.
    Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
    injected into the PLL circuitry via VDDSYN and VSSSYN and variation in crystal oscillator frequency increase the jitter percentage
    for a given interval. CLKOUT divider is set to divide-by-two.
    14 Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of (jitter + Cmod).
    15 Modulation depth selected must not result in f
    sys value greater than the fsys maximum specified value.
    16 f
    sys = fico (2
    RFD).
    17 The ICO frequency can be higher than the maximum allowable system frequency. For this case, set the FMPLL synthesizer
    control register reduced frequency divider (FMPLL_SYNCR[RFD]) to divide-by-two (RFD = 0b001). Therefore, for a 40 MHz
    maximum device (system frequency), program the FMPLL to generate 80 MHz at the ICO output and then divide-by-two the
    RFD to provide the 40 MHz clock.
    18 Maximum value for dual controller (1:1) mode is (f
    MAX 2) with the predivider set to 1 (FMPLL_SYNCR[PREDIV] = 0b001).
