Oscillators Procurement Notes

Verify the specific suffix '-OE' against the manufacturer's current datasheet to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD package dimensions match the PCB footprint specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 2.7405 MHz reference is required in space-constrained designs. The 1.8V operation makes it suitable for modern low-power digital systems. Consider the ±50ppm stability for applications not requiring high-precision timing. The enable pin allows for dynamic power control during idle states.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The '18' prefix typically indicates the 1.8V supply variant. The 'QHTF' designation relates to the specific package and performance class within the manufacturer's portfolio.

Oscillators Replacement Considerations

Direct substitutes must match the 2.7405 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar small-form-factor XO components.
