representation of the internal components and may not represent actual
circuitry. The oscillator configuration uses five components:
⢠Crystal, X1
⢠Fixed capacitor, C1
⢠Tuning capacitor, C2 (can also be a fixed capacitor)
⢠Feedback resistor, RB
⢠Series resistor, RS (optional)
The series resistor (RS) may not be required for all ranges of operation,
especially with high-frequency crystals. Refer to the crystal
manufacturerâs data for more information.
Figure 3 also shows the external components for the PLL:
⢠Bypass capacitor, CBYP
⢠Filter capacitor, CF
Routing should be done with great care to minimize signal cross talk and
noise. (See Acquisition/Lock Time Specifications on page 126 for
routing information and more information on the filter capacitorâs value
and its effects on PLL performance).
