Appendix A Electrical Characteristics
A.5.3
The oscillator provides the reference clock for the PLL. The PLL´s Voltage Controlled Oscillator (VCO)
is also the system clock source in self clock mode.
A.5.3.1
This section describes the selection of the XFC components to achieve a good filter characteristics.
The following procedure can be used to calculate the resistance and capacitance values using typical values
for K
The VCO Gain at the desired VCO output frequency is approximated by:
The phase detector relationship is given by:
i
The loop bandwidth f
typical values are 50. = 0.9 ensures a good transient response.
