Oscillators Procurement Notes

Verify the specific package variant, as datasheets may list both 3.2x2.5mm and 2.5x2.0mm footprints for similar part numbers. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory updates can occur. Ensure the design-in includes proper decoupling capacitors near the VDD pin to maintain signal integrity and meet the specified jitter performance requirements.

Oscillators Selection Notes

Select this component when a balance between size, power consumption, and frequency stability is required. The MEMS construction offers superior shock tolerance over ceramic resonators. Consider the ±25ppm stability sufficient for most digital logic applications. Verify that the 3.3V logic level matches the target system's input thresholds before finalizing the design.
