Procurement Notes
Verify the specific frequency suffix matches the required 13.494 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package dimensions are compatible with the PCB footprint. Check for any specific operating temperature range requirements against the datasheet.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable pin allows for system-level power optimization. Consider the leadless package profile for space-constrained designs. Validate frequency stability needs against the standard XO specifications provided in the official documentation.
Part Context
Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in frequency control products including quartz crystals and oscillators. This part belongs to their series of standard crystal oscillators designed for general-purpose timing applications in electronic devices.
Replacement Considerations
Cross-reference other 18QHTF21 series variants from Mercury Electronics for different frequencies. Verify electrical compatibility with alternative manufacturers offering 4-SMD LVCMOS oscillators at 1.8V before substitution.
