18QHTF21-61.875-OE

Overview

The 18QHTF21-61.875-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 61.875 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control capability
• Surface-mount design with no lead construction

Applications

• General purpose clock signal generation
• Digital communication systems
• Microprocessor timing references

Procurement Notes

Verify the specific ordering suffix and voltage requirements against the target application schematic. Confirm that the 1.8V supply rail is stable and within operational limits. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions provided in the official datasheet to prevent assembly errors.

Selection Notes

Select this component when a 61.875 MHz frequency is required with low-voltage operation. Consider the enable/disable feature if power management or signal gating is necessary. Evaluate the package size constraints against available board space. Compare performance metrics such as jitter and stability against system requirements before finalizing the choice.

Part Context

This part belongs to the QHTF series of standard oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'OE' suffix typically denotes specific packaging or testing configurations defined by the manufacturer. This model represents a fixed-frequency solution within their broader portfolio of quartz-based timing devices.

Replacement Considerations

Direct substitutes must match the 61.875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics with alternative manufacturers. Cross-reference part numbers from other suppliers offering equivalent specifications.
