18QHTF21-13.081-OE

Overview

The 18QHTF21-13.081-OE is a standard frequency XO oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.081 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.

Feature Summary

• LVCMOS output interface for digital system compatibility
• Integrated enable/disable pin for power optimization
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing circuits
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout guidelines to prevent assembly issues.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable feature makes it suitable for battery-powered or power-sensitive designs. Consider the small form factor if board space is limited compared to larger oscillator packages.

Part Context

This part belongs to Mercury's QuikXO series, which focuses on fast-delivery CMOS output clock oscillators. The manufacturer specializes in quartz crystals and timing solutions, offering both standard and custom frequencies built to order. This series emphasizes quick turnaround times for production needs.

Replacement Considerations

Check for direct substitutes within the same QuikXO series that match the 13.081 MHz frequency and 1.8V supply. Verify pinout compatibility for the 4-SMD package before replacing. Cross-reference electrical specifications to ensure equivalent performance in your application.
