Procurement Notes

Verify the specific suffix OE against manufacturer documentation to confirm package type and pinout configuration. Ensure the operating temperature range meets system requirements. Cross-reference the frequency tolerance specifications with design constraints. Confirm that the 1.8V supply voltage aligns with the target circuit's power rails before procurement.

Selection Notes

Select this component when a precise 86.95 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V supply requirement and the enable/disable feature for power-sensitive designs. Evaluate the 2.0x1.6 mm footprint against available PCB space. Compare load capacitance requirements with the crystal specifications to ensure stability.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency references. The 18QHTF21 prefix indicates a specific family of surface-mount oscillators. Similar models in this series may offer different frequencies or supply voltages, such as 3.3V variants. The OE suffix typically denotes a specific packaging or tape-and-reel configuration.

Replacement Considerations

Direct substitutes must match the 86.95 MHz frequency, LVCMOS output, and 1.8V supply voltage. Verify package compatibility with the 2.0x1.6 mm footprint. Check if alternative manufacturers offer equivalent performance metrics. Ensure thermal characteristics and aging rates are comparable for long-term reliability.
