18QHTF21-25.088-OE

Oscillators Overview

The 18QHTF21-25.088-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 25.088 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function for power management. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable functionality for active power control
• Utilizes a leadless surface-mount package for space-constrained designs

Oscillators Applications

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

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 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a precise 25.088 MHz reference is required for LVCMOS-compatible digital circuits. Consider the 1.8V operating voltage constraint and the need for an enable pin to manage standby power states. The small 2.0x1.6 mm form factor makes it suitable for high-density board layouts where space efficiency is critical compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. The series offers various frequencies within a consistent 2.0x1.6 mm SMD package. The suffix -OE indicates the inclusion of an enable/disable control feature, distinguishing it from basic models without pin control. This family targets consumer electronics and portable devices requiring reliable timing signals.

Oscillators Replacement Considerations

Direct substitutes include other 25.088 MHz LVCMOS oscillators in 4-SMD 2.0x1.6mm packages with 1.8V operation and enable pins. Verify electrical compatibility regarding current consumption and drive strength. Mechanical footprint matching is essential for drop-in replacement without PCB redesign.
