18QHTF21-21.1184-OE

Oscillators Overview

The 18QHTF21-21.1184-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 21.1184 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
• Enable/Disable control functionality
• Compact 4-SMD No Lead package

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm enable/disable pin configuration and tolerance specifications. Ensure compatibility with 1.8V supply rails and LVCMOS logic thresholds before integration. Cross-reference the 4-SMD no lead footprint dimensions with PCB layout guidelines to prevent assembly errors.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside active power control capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 4-SMD no lead form factor for high-density board designs where space constraints are critical.

Oscillators Part Context

This oscillator belongs to the Mercury Electronics XO series, which specializes in quartz-based frequency control products. The company has decades of experience in manufacturing crystals and oscillators, positioning itself as a pioneer in the Taiwan quartz industry. This model represents their standard surface-mount oscillator offerings.

Oscillators Replacement Considerations

Direct substitutes must match the 21.1184 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no lead package. Verify that alternative components support the same enable/disable control mechanism and meet identical electrical performance criteria.
