Oscillators Procurement Notes

Verify the specific ordering suffix against the official SiTime datasheet to ensure correct voltage, package, and tolerance specifications. Confirm that the 2.8V supply requirement aligns with the target system design. Check RoHS compliance status as indicated in manufacturer documentation. Ensure the lead time and availability are confirmed through authorized distributors, as stock levels may vary. Cross-reference the part number with the latest revision to avoid obsolete configurations.

Oscillators Selection Notes

Select this component when a small form factor and moderate stability are required for 66.666660 MHz applications. The 2.0x1.6 mm package is suitable for dense PCB layouts where larger oscillators cannot fit. Consider the 2.8V supply constraint during power budget analysis. This model is appropriate for designs needing LVCMOS outputs without additional buffering. Evaluate thermal requirements to ensure operation within the -20°C to +70°C range.
