Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency and voltage levels. Confirm that the 1.8V supply requirement aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small physical footprint. The LVCMOS output is suitable for standard digital logic interfaces. Consider the standby feature if power efficiency during idle periods is a critical design parameter for the application.

Oscillators Part Context

This model belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages, utilizing standard quartz crystal technology. The 18QHTF21 variant specifically denotes the 1.8V supply and 2.0x1.6mm package size within the product line.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 models with different frequencies, such as 18QHTF21-51.200-PD or 18QHTF21-96.768-PD, provided the frequency change is acceptable. Cross-brand replacements require matching voltage, package, and output logic specifications.
