Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's specifications to ensure accurate frequency performance. Ensure the PCB footprint matches the 2.0x1.6mm 4-SMD no-lead package dimensions provided in the official datasheet.

Oscillators Selection Notes

Select this component when a precise 25.48828 MHz timing source is required within a 1.8V logic environment. The enable pin allows for dynamic power control, making it suitable for battery-operated devices. Consider the small form factor if space constraints are critical in the layout design.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options. The 'OE' suffix indicates the inclusion of an enable/disable control feature, distinguishing it from standard continuous-output variants within the same package family.

Oscillators Replacement Considerations

Direct substitutes must match the 25.48828 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify that any alternative component supports the enable/disable function if power management is required in the application.
