18QHTF21-25.000938-OE

Oscillators Overview

The 18QHTF21-25.000938-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 25.000938 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features enable/disable control functionality for power management
• Utilizes a leadless SMD package for space-constrained designs

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable frequency sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the enable/disable pin configuration matches your control logic to prevent unintended operation states during deployment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS outputs are required. Consider the enable/disable feature if power conservation or dynamic clock gating is necessary. Verify that the 4-SMD no-lead footprint fits within the PCB layout constraints compared to larger packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based timing solutions. The series typically offers various frequencies and voltage levels. This specific model targets applications needing a precise 25 MHz class signal with low power consumption and small form factor integration.

Oscillators Replacement Considerations

Direct substitutes must match the 25.000938 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify electrical parameters such as frequency stability and phase noise specifications to ensure functional equivalence in the target application.
