18QHTF21-109.260-OE

Overview

The 18QHTF21-109.260-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 109.26 MHz and utilizes LVCMOS output logic. 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 assembly on printed circuit boards.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital system timing references
• Embedded electronic circuits requiring stable frequency sources

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct voltage and output specifications. Confirm that the 1.8V supply requirement aligns with the target system design. Check for any specific handling or storage requirements detailed in the component datasheet prior to procurement.

Selection Notes

Select this component when a 109.26 MHz clock source with LVCMOS outputs is required. Ensure the design accommodates the 1.8V operating voltage and the physical dimensions of the 4-SMD package. Consider the enable/disable feature if power efficiency during idle states is a design priority.

Part Context

This oscillator belongs to the Mercury Electronics XO series, which provides standard frequency solutions. The model designation indicates a 1.8V operation and LVCMOS output type. It is distinct from differential oscillators or other voltage variants within the manufacturer's broader portfolio.

Replacement Considerations

Direct substitutes must match the 109.26 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical parameters before swapping with components from other manufacturers.
