18QHTF21-12.285-OE

Overview

The 18QHTF21-12.285-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.285 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications.

Feature Summary

• LVCMOS output interface
• Enable/Disable control capability
• Compact SMD form factor

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints to avoid assembly issues.

Selection Notes

Select this component when a precise 12.285 MHz reference is required with low voltage operation. Consider the enable pin feature if power conservation is critical. Compare performance metrics such as phase noise and stability against other oscillators in the same family to ensure compatibility with your application's timing sensitivity.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics. The -OE suffix typically denotes a specific packaging or tape-and-reel configuration, though exact details require datasheet verification. It is designed for general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 12.285 MHz LVCMOS oscillators with identical 1.8V supply and 4-SMD no-lead packages. Verify pinout compatibility and electrical specifications before substitution. Consult manufacturer cross-reference lists for validated replacements.
