18QHTF21-24.772608-OE

Oscillators Overview

The 18QHTF21-24.772608-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.772608 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated enable and disable functionality for power management
• Utilizes a leadless SMD package for automated assembly integration

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded controller clock sources

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 rail stability meets the oscillator's operational specifications to ensure signal integrity. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official mechanical drawing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature makes it suitable for power-sensitive designs. Consider the leadless package type for high-density board layouts where standard pin headers are impractical.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which specializes in quartz-based timing solutions. The manufacturer has extensive experience in Taiwan's quartz industry since 1973. This specific part represents a standard frequency option within their broader portfolio of surface-mount oscillators.

Oscillators Replacement Considerations

Direct substitutes must match the 24.772608 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
