The PLL loop filter has two bandwidths which are automatically selected. When the
PLL is first enabled, the wide bandwidth mode is used which enables the PLL fre-
quency to ramp up quickly. Then when the output frequency is near the desired
frequency, the filter is switched to the narrow bandwidth to make the final frequency
more stable. The PLL requires an external filter network on XFC.

different filter values (first order affect is multiplication factor N, based on W and Y bits
in the SYCNR register). Leakage from the XFC pin must not be greater than that of a
15-m resistor to meet jitter specifications. If the PLL is not enabled, then the XFC fil-
ter is not required and the pin may be left unconnected.
The VCO will oscillate at a frequency dictated by the voltage coming out of the filter
circuit. To save system power, the VCO is shut off when it is not needed.
