Applications
7.1
Applications schematic and power supplies
Figure 17 below shows a circuit diagram of a typical application for STA335BWSQS.
Particular care has to be given to the layout of the PCB, especially the power supplies. The
3.3-
Ω resistors on the digital supplies (VDD_DIG) have to be placed as close as possible to
the device. This helps to prevent unwanted oscillation on the digital portion of the device due
to inductive tracks of the PCB. This same rule also applies to all the decoupling capacitors in
order to limit any kind of spikes on the supplies.
Figure 17.
Application schematic
7.2
PLL filter schematic
It is recommended to use the schematic and values in Figure 18 below for the PLL loop
filter. In order to achieve the best performance from the device in general applications the
filter ground (PLL_GND) must be connected as close as possible to the device pin
PLL_GND. 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.
