Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required frequency, voltage, and package dimensions. Confirm the output format aligns with system logic requirements. Ensure the temperature grade meets environmental specifications. Cross-reference the manufacturer part number against official SiTime documentation to avoid substitution errors. Validate RoHS compliance status if required by project standards.

Oscillators Selection Notes

Select this component when design constraints demand low power consumption alongside high reliability in a small form factor. The MEMS architecture eliminates sensitivity to mechanical stress common in quartz devices. Consider the ±50 ppm stability sufficient for general digital clocking needs. Evaluate the 3.3 V supply requirement against available board power rails. The enable pin allows for power management strategies in battery-operated designs.

Oscillators Part Context

This model belongs to the SiT8008 series, which represents SiTime's low-power programmable MEMS oscillators. The series supports frequencies from 1 to 110 MHz across multiple package options. It is designed to replace traditional quartz crystals and oscillators in applications where size, weight, and robustness are critical factors.

Oscillators Replacement Considerations

Direct replacements must match the 66.66 MHz frequency, 3.3 V supply, and 2520 package. Verify equivalent stability and output drive strength. Consult SiTime's cross-reference tools for compatible alternative part numbers within the same family or series.
