This section gives some design guidelines that must be respected for good oscillator design.

●

A large stray capacitance and large inductances must be kept to a minimum to avoid an

undesired mode of oscillation, and problems with startup. In addition, high frequency

signals should be avoided near the oscillator circuitry.

●

Trace lengths should be kept as short as possible. Ground plans should be used to

isolate signals and reduce noise.
