Use the 30% value for initial operation
Recommend connecting appropriate power supply bypass capacitors as close as
possible.
Layout and application information
For Optimum Jitter Performance, Pletronics recommends:
•
Minimize air flow over the oscillator
•
Stabilize the power supply voltage for best performance.
