18QHTF21-10.58144-OE

Overview

The 18QHTF21-10.58144-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.58144 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable 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 controller clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper solder joint integrity and mechanical stability during operation.

Selection Notes

Select this component when a precise 10.58144 MHz clock source is required for LVCMOS-compatible circuits. The choice is driven by the need for low-voltage operation at 1.8V and the space constraints addressed by the small 4-SMD form factor. Consider the enable/disable feature if power management strategies require active clock gating during idle periods within the electronic system.

Part Context

This part belongs to the Mercury Electronics XO series, which includes various frequencies such as 31.744 MHz and 44.2 MHz. These oscillators share common characteristics like LVCMOS outputs and SMD packaging. The manufacturer has a long history in quartz crystal production, positioning these components within their standard frequency control product lineup for industrial and consumer electronics.

Replacement Considerations

Direct substitutes include other 10.58144 MHz LVCMOS oscillators in similar packages from different manufacturers. Verify pinout compatibility and electrical specifications before substitution. Cross-referencing with Mercury's other models in the same series may provide alternatives with adjusted tolerances or temperature ranges.
