18QHTF21-63.888-OE

Overview

The 18QHTF21-63.888-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 63.888 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an integrated enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Feature Summary

• LVCMOS output interface
• 1.8V supply voltage operation
• Enable/Disable control functionality

Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics circuits

Procurement Notes

Verify the specific suffix 'OE' against official Mercury Electronics documentation to confirm the enable/disable feature and voltage specifications. Ensure the 4-SMD no-lead package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 63.888 MHz clock source with LVCMOS outputs is required. Consider the 1.8V operating voltage constraint and the need for an enable pin. Evaluate the 4-SMD package size against available board space and thermal management needs.

Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies and voltage options. Similar models like the 18QHTF21-37.888-OE share the same package and logic type but differ in frequency. The product line focuses on quartz-based frequency control solutions.

Replacement Considerations

Direct substitutes must match the 63.888 MHz frequency, 1.8V LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters with alternative manufacturers before implementation.
