Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your power management architecture. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable attachment.

Oscillators Selection Notes

Select this component when a precise 26.563828 MHz reference is required for LVCMOS-compatible digital interfaces. Consider the 1.8V operating voltage for low-power designs. Evaluate the thermal performance and stability needs against the standard XO specifications. Ensure the physical dimensions of the 4-SMD package fit within the available board space constraints.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. These components are designed for general-purpose timing applications where size and power efficiency are prioritized over ultra-high stability metrics found in TCXO or OCXO variants.

Oscillators Replacement Considerations

Direct substitutes must match the 26.563828 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as rise/fall times. Cross-reference with other manufacturers offering identical form-factor and electrical specs for equivalent performance.
