Clock and Board Guidelines

C
The maximum noise allowed on XFC is 50 mV peak-to-peak with a typical cut-off frequency of 500 Hz.
The XFC capacitor creates a low pass filter in the PLL loop. The filter output feeds the PLL VCO. The
capacitor is charged and discharged by short current pulses, generated by the phase detector. So the
capacitor leakage and absorption directly affect the AC component in the VCO input voltage that creates
PLL output clock jitter. Therefore, the dielectric quality of C

Note: A filter cut off frequency of 500Hz is recommended, however this will result in a
capacitor size of 33uF using a 10 Ohm resistor. This may be too expensive or large
for the system. In this case the filter shown with cut- off frequency of 160kHz will suffice.
Note: A filter cut off frequency of 500Hz is recommended, however this will result in a
capacitor size of 15uF using a 8.2mH inductor. This may be too expensive or large
for the system. In this case the filter shown with cut- off frequency of 5.5kHz will suffice.
