18QHTF21-25.010-OE

Oscillators Overview

The 18QHTF21-25.010-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 25.010 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications. The component is engineered to provide stable clock signals within specified operating temperature ranges, suitable for digital circuit timing requirements.

Oscillators Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated enable/disable functionality for power optimization
• Surface-mount 4-SMD no-lead package design

Oscillators Applications

• Digital system clock generation
• Microcontroller timing sources
• Communication interface synchronization

Oscillators Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct voltage and output configuration. Confirm that the OE suffix aligns with the required enable/disable feature set. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Ensure the selected variant matches the target PCB footprint and thermal requirements.

Oscillators Selection Notes

Select this component when a 25.010 MHz LVCMOS signal is required with low-voltage operation. Consider the 1.8V supply constraint and the necessity for an enable pin during system design. Evaluate the 4-SMD package dimensions against available board space. Compare performance specifications against alternative oscillators if stricter jitter or stability metrics are needed for the application.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and packages. The series typically includes models with different output voltages and load conditions. This specific model represents a standard XO variant, distinct from TCXO or VCXO types, focusing on basic frequency stability without external compensation or tuning capabilities.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-25.000 or 18QHTF21-25.175, provided the frequency difference is acceptable. Verify package compatibility and voltage levels before substitution.
