PLL filter circuit

It is recommended to use the applications 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.
