18QHTF21-22.275-OE

Oscillators Overview

The 18QHTF21-22.275-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 22.275 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 applications requiring precise timing signals.

Oscillators Feature Summary

• Integrates enable/disable functionality for active power control
• Delivers stable LVCMOS clock signals at 22.275 MHz
• Utilizes a low-profile 4-SMD no-lead surface mount package

Oscillators Applications

• Digital signal processing systems requiring precise clocking
• Communication equipment utilizing LVCMOS interfaces
• Embedded systems with 1.8V power domains

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a 22.275 MHz reference is required for LVCMOS-compatible digital circuits. The integrated enable pin offers flexibility for power-sensitive designs. Consider the 1.8V operating voltage constraint and ensure compatibility with the host controller's I/O levels. The small form factor suits high-density board layouts where space is limited.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically features low-power consumption and robust performance across industrial temperature ranges. The 'OE' suffix indicates the inclusion of an enable/disable control feature, distinguishing it from standard continuous-output variants within the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 22.275 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if available. Cross-reference with other manufacturers offering equivalent SMD oscillators with identical envelope dimensions.
