- Electronic device synchronization
Procurement Notes
Verify the specific part number against official Mercury Electronic Ind. Co. Ltd documentation to ensure accuracy. Confirm that the 1.8V supply voltage and LVCMOS output requirements align with the target circuit design. Check for any specific ordering suffixes or variations that may affect electrical characteristics or packaging details before finalizing procurement.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The small 4-SMD footprint makes it suitable for space-constrained designs. Ensure the application supports the enable/disable feature if power management is a priority. Verify temperature range specifications against operational environments.
Part Context
This oscillator belongs to the 18QHTF series from Mercury Electronic Ind. Co. Ltd, a supplier specializing in quartz crystals and oscillators. The company has a long history in Taiwan's frequency-control industry. This specific model provides precise timing solutions using standard surface-mount technology.
Replacement Considerations
Direct substitutes include other models within the same series such as the 18QHTF21-37.200-OE or 18QHTF21-96.768-OE, provided the frequency difference is acceptable. Cross-referencing with similar LVCMOS oscillators from other manufacturers requires careful verification of pinout and voltage levels.
