Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the enable/disable feature set. Ensure the 1.8V supply requirement aligns with target board design. Confirm the 4-SMD no lead footprint matches PCB layout constraints before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 25.768 MHz clock source with low voltage operation is required. The LVCMOS output suits logic families compatible with 1.8V levels. Consider the enable/disable pin if power management during idle states is necessary for the application design.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, specifically utilizing the QHTF21 package code. The prefix 18 indicates the operating voltage class. This model represents a standard frequency option within their quartz-based oscillator portfolio, distinct from differential or spread spectrum variants.

Oscillators Replacement Considerations

Cross-reference with other Mercury models sharing the QHTF21 footprint and 1.8V LVCMOS specification. Verify that substitute parts support the same enable/disable control mechanism and 25.768 MHz frequency tolerance.
