1.
Using a Discrete “Chip” Inductor If the required value for LEXT is greater than 3 nH, it is recommended that a discrete “chip” inductor be used.
This inductor should be placed as close as possible to the device pins as shown in Figure 1.
printed trace Silicon Laboratories’ family of frequency synthesizers integrates VCOs, loop filters, reference and VCO dividers, and phase detectors in standard CMOS technology.
Depending on the synthesizer being used, the frequency of operation may require an external inductance to establish the desired center frequency of operation.
This may ...
