Oscillators Procurement Notes

Verify the specific operating voltage and frequency requirements against the target circuit design before procurement. Confirm that the 1.8V supply rail is stable and compatible with the LVCMOS logic thresholds. Ensure the PCB footprint matches the 4-SMD no-lead package specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 25.009 MHz reference is required within space-constrained designs. The 1.8V supply requirement makes it suitable for low-power portable applications. Consider the enable pin utility if dynamic power saving is necessary. Verify thermal performance and load capacitance requirements against the host microcontroller or FPGA specifications.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The '18' prefix indicates the 1.8V operating voltage variant. The 'OE' suffix denotes the inclusion of an enable control feature, distinguishing it from standard continuous-output models within the same physical package family.

Oscillators Replacement Considerations

Direct replacements must match the 25.009 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers offering identical electrical characteristics and pinout configurations to ensure seamless integration without circuit redesign.
