18QHTF21-7.9365079-OE

Overview

The 18QHTF21-7.9365079-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.9365079 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. 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 automated assembly

Applications

• General clock signal generation
• Digital system timing references
• Embedded controller circuits

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 power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions to prevent soldering defects during assembly.

Selection Notes

Select this component when a low-voltage LVCMOS oscillator is required for space-constrained designs. The enable pin allows for power management strategies in battery-operated devices. Consider the operating temperature range and stability requirements relative to the application environment.

Part Context

This part belongs to the Mercury Electronics XO series, which focuses on standard frequency control solutions. The manufacturer specializes in quartz-based components including crystals and oscillators. This specific model represents a single-ended output variant within their portfolio.

Replacement Considerations

Direct substitutes must match the 7.9365079 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics before cross-referencing alternative manufacturers.
