18QHTF21-14.3181-OE

Oscillators Overview

The 18QHTF21-14.3181-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 14.3181 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise timing signals in low-voltage digital circuits.

Oscillators Feature Summary

• Supports LVCMOS output logic for compatibility with standard digital interfaces
• Includes enable/disable functionality for power management control
• Utilizes a small form factor 4-SMD no lead package design

Oscillators Applications

• General purpose clock generation for digital systems
• Timing reference for microcontrollers and processors
• Data communication interface synchronization

Oscillators Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against your specific circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliability.

Oscillators Selection Notes

Select this component when a 14.3181 MHz clock signal is required with LVCMOS outputs. Consider the 1.8V operating voltage constraint compared to other available voltage options like 2.5V or 3.3V. Evaluate the space constraints as the 2.0x1.6mm package is quite small. Verify if the enable/disable feature is necessary for your power management strategy. Compare performance metrics such as phase noise and stability if high precision is critical for the application.

Oscillators Part Context

This part belongs to the QHTF series of surface mount crystal oscillators from Mercury Electronic. The series offers various frequencies and voltage options. The '18' prefix indicates the 1.8V supply variant. The 'OE' suffix typically denotes the enable pin configuration. Mercury Electronic is a specialized supplier of frequency control products including crystals and oscillators.

Oscillators Replacement Considerations

The 25QHTF21-14.3181-OE is a similar oscillator but operates at 2.5V instead of 1.8V. Direct replacement requires verifying voltage compatibility. Other parts in the QHTF series may offer different frequencies or packages. Always consult the official datasheet for electrical parameter comparisons before substituting.
