Procurement Notes

Verify the specific ordering suffix and package variant against the official Crystek datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and environmental classifications prior to procurement. Ensure that the supplier provides valid traceability documentation. Cross-reference the part number with authorized distributor lists to avoid counterfeit components. Validate that the received units match the active product status indicated in manufacturer catalogs.

Selection Notes

Select this component when a stable 44 MHz center frequency is required within a narrow tuning range. Consider the 16-QFN form factor for space-constrained PCB layouts. Evaluate the -13 dBc second harmonic performance against system spectral purity requirements. Assess the 0.5 MHz/V pushing factor for sensitivity to supply noise. Ensure the 5V supply rail aligns with existing system power architecture.
