Procurement Notes

Verify the specific operating temperature range and supply voltage requirements against the official datasheet before procurement, as variations exist within the CFPS-73 family. Confirm that the 50 ppm stability meets system timing tolerances. Ensure the 3.3 V logic level compatibility aligns with the target circuit's input thresholds. Check for any recent part number revisions or alternate packaging options such as Reel or Cut Tape availability through authorized distributors.

Selection Notes

Select this component when a 50 MHz reference signal is required with moderate stability. The 7x5mm footprint suits space-constrained designs. Verify that the HCMOS output swing matches downstream logic inputs. Consider thermal performance if the application exceeds standard commercial temperature limits. Evaluate power consumption relative to other oscillators in the same series to ensure system efficiency targets are met.

Part Context

This oscillator belongs to the CFPS-73 series, which offers various frequencies and stabilities in a standardized 7x5mm package. It serves as a fundamental timing element in modern electronic assemblies. The series provides a balance between performance and size, catering to applications requiring reliable clock generation without the complexity of programmable devices. It complements IQD's broader portfolio of frequency control solutions.

Replacement Considerations

Direct substitutes may include other 50 MHz HCMOS oscillators in the 7x5mm package from IQD or competitors, provided pinout and electrical characteristics match. Verify equivalent stability (50 ppm) and voltage range. Cross-reference with LFSPXO019835 for similar form factor but different frequency. Ensure functional compatibility regarding enable/disable behavior and output drive strength.
