6 Self clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls outside
the fLOR window.
7 f
VCO self clock range is 20–150 MHz. fSCM represents fSYS after PLL output divider (ERFD) of 2 through 16 in
enhanced mode.
8 This value is determined by the crystal manufacturer and board design.
9 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 VDDPLL and VSSPLL and variation in crystal oscillator frequency increase the
CJITTER percentage for a given interval.
10 Proper PC board layout procedures must be followed to achieve specifications.
11 Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of C
JITTER and
either fCS or fDS (depending on whether center spread or down spread modulation is enabled).
12 This value is determined by the crystal manufacturer and board design. For 4 MHz to 20 MHz crystals specified for
this PLL, load capacitors should not exceed these limits. For a 20 MHz crystal the maximum load should be 17 pF.
13 Proper PC board layout procedures must be followed to achieve specifications.
14 This parameter is guaranteed by design rather than 100% tested.
15 Vxtal range is preliminary and subject to change pending characterization data.
16 V
IHEXT cannot exceed VRC33 in external reference mode.
17 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).
18 Modulation depth will be attenuated from depth setting when operating at modulation frequencies above 50kHz.
