18QHTF21-25.00003-OE

Oscillators Overview

The 18QHTF21-25.00003-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 25.00003 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, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Digital signal processing systems
• Communication equipment timing circuits
• Consumer electronics requiring precise clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target system design before procurement. Confirm that the 1.8V supply voltage aligns with the power architecture. Ensure the 4-SMD no-lead footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management strategies in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs where standard leaded packages are unsuitable.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency generation solutions. The model number indicates a 25 MHz variant within the 18QHTF21 family, characterized by its specific pinout and electrical parameters tailored for modern low-power electronic applications.

Oscillators Replacement Considerations

Direct substitutes must match the 25.00003 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify equivalent enable/disable functionality and operating temperature range to ensure seamless integration without circuit modification.
