18QHTF21-12.888-OE

Overview

The 18QHTF21-12.888-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.888 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.

Feature Summary

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

Applications

• Digital clock signal generation
• Data communication interfaces
• Embedded system timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a low-voltage LVCMOS output is required for timing applications. Consider the enable/disable feature if power management or clock gating is necessary. Evaluate the operating temperature range and stability specifications to ensure reliability under environmental conditions.

Part Context

This model belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The 18QHTF21 prefix indicates a specific form factor and performance class within their oscillator lineup, distinct from TCXOs or VCXOs.

Replacement Considerations

Cross-reference with other 12.888 MHz LVCMOS oscillators in 4-SMD packages. Verify pinout compatibility and electrical parameters before substitution.
