Applications
Applications schematic

has to be paid to the layout of the PCB. All the decoupling capacitors have to be placed as
close as possible to the device to limit spikes on all the supplies.
PLL filter circuit
It is recommended to use the above circuit and values for the PLL loop filter to achieve the
best performance from the device in general applications. Note that the ground of this filter
circuit has to be connected to the ground of the PLL without any resistive path. Concerning
the component values, it must be taken into account that the greater the filter bandwidth, the
less is the lock time but the higher is the PLL output jitter.
