Internal voltage reference
An embedded voltage regulator produces the reference voltages for the DMOS bridge
driver. It requires two 100 nF capacitors to keep the regulator stable. The capacitors should
be place close to the pins.

PLL filter schematic
It is recommended to use the below scheme and values for the PLL loop filter to achieve the
best performances from the device in general application. Please be noted that the ground
of this filter scheme has to be connected to the ground of the PLL without any resistive path.
Concerning the component values, please take into account that the greater is the filter
bandwidth, the less is the lock time but the higher is the PLL output jitter.
