7.9.3 Choosing a Filter
MC68HC908GR8 — Rev 4.0
MOTOROLA
As described in
filter network is critical to the stability and reaction time of the PLL. The
PLL is also dependent on reference frequency and supply voltage.
Either of the filter networks in
a 32.768-kHz reference crystal. In low-cost applications, where stability
and reaction time of the PLL is not critical, this filter network can be
replaced by a single capacitor.
