Oscillators Procurement Notes

Verify the specific frequency suffix matches the required system clock speed. Confirm that the 1.8V supply voltage aligns with the target circuit's power domain. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check the package dimensions against the PCB footprint library to guarantee mechanical fit during assembly.

Oscillators Selection Notes

Choose this component when a low-voltage 1.8V supply is available and LVCMOS signaling is required. The enable/disable feature allows for dynamic power savings in battery-operated devices. Consider the operating temperature range if the application involves harsh environmental conditions. Verify that the small form factor meets the spatial constraints of the design.

Oscillators Part Context

This part belongs to the QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The '18' prefix indicates the 1.8V supply variant. The '-OE' suffix typically denotes specific ordering or packaging configurations defined by the manufacturer.

Oscillators Replacement Considerations

Direct substitutes include other 1.8V LVCMOS oscillators in 4-SMD packages with similar frequency stability. Verify pin compatibility and electrical specifications before substitution. Cross-reference with Mercury's own variants such as the 3QHTF21 series for different voltage requirements.
