18QHTF21-67.10886-OE

Overview

The 18QHTF21-67.10886-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 67.10886 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature 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 circuit compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Applications

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

Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout configuration and electrical tolerances. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the 4-SMD no-lead package dimensions match the PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this component when a stable 67.10886 MHz reference is required for low-voltage digital interfaces. The LVCMOS output simplifies integration with standard logic families. Consider the enable/disable functionality if power efficiency during idle states is a critical design constraint for the application.
