18QHTF21-68.085-OE

Overview

The 18QHTF21-68.085-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 68.085 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package designed for surface mount applications.

Feature Summary

• LVCMOS output interface compatible with standard digital logic circuits
• Integrated enable/disable functionality for active power control
• Surface mount construction suitable for automated assembly processes

Applications

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

Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the enable/disable feature set. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD no lead package dimensions match the PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise 68.085 MHz timing. The enable pin allows for dynamic power savings in battery-operated systems. Consider the thermal operating range and stability specifications relative to the application environment constraints.

Part Context

This part belongs to the QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 18 prefix indicates the 1.8V supply variant, while the OE suffix denotes the enable capability within the standard XO product line.

Replacement Considerations

The 18QHTF21-68.085-PD is a related variant featuring standby power down instead of simple enable/disable. Verify functional equivalence regarding control logic before substitution.
