SiTime recommends a 4-layer PCB with a solid ground plane, and to keep the oscillator away from high-frequency signals and noise sources. A good layout practice is to use a star topology for the power supply and to decouple the oscillator with a 0.01uF capacitor.
To ensure the oscillator starts up correctly, make sure the power supply is stable and within the recommended range, and that the oscillator is properly decoupled. Also, ensure that the load capacitance is within the recommended range and that the oscillator is not subjected to excessive noise or EMI.
The recommended termination for the output is a 15pF to 30pF capacitor in series with a 1kΩ to 2kΩ resistor, depending on the specific application and load requirements.
To minimize EMI and RFI, use a shielded enclosure, keep the oscillator away from antennas and other EMI sources, and use a common-mode choke or ferrite bead on the power supply lines. Also, ensure good PCB layout practices, such as keeping the oscillator signal traces short and away from noise sources.
The SIT8209AI-21-33S-100.000000X oscillator is rated for operation from -40°C to +85°C, but it can be customized for extended temperature ranges upon request.
