18QHTF21-4.87424-OE

Oscillators Overview

The 18QHTF21-4.87424-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fundamental frequency of 4.87424 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded controller clock inputs

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly errors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 4.87424 MHz frequency specifically for applications requiring this exact harmonic or division ratio rather than standard integer multiples.

Oscillators Part Context

This part belongs to the Mercury Electronic XO series, which provides quartz-based timing solutions. Mercury Electronics is a Taiwan-based manufacturer specializing in frequency control products including crystals, oscillators, and filters. This specific model represents a standard frequency option within their broader portfolio of surface-mount oscillators.

Oscillators Replacement Considerations

Direct substitutes must match the 4.87424 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility for the enable/disable function. Cross-reference with other manufacturers offering identical electrical specifications and mechanical footprints to ensure interchangeability.
