18QHTF21-7.6275-OE

Overview

The 18QHTF21-7.6275-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.6275 MHz and utilizes LVCMOS output logic levels. The device supports an enable/disable control function and is powered by a 1.8V supply voltage. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

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

Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Procurement Notes

Verify the specific frequency suffix matches the required 7.6275 MHz specification. Confirm that the 1.8V operating voltage aligns with the target system power rails. Ensure the 4-SMD no-lead footprint is compatible with the PCB design. Check for any specific environmental or reliability certifications if required for the application.

Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor for space-constrained designs. Verify that the standard XO stability meets the system jitter requirements.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD package. The series provides LVCMOS outputs with enable controls, catering to modern low-power digital applications. Mercury Electronics specializes in quartz crystals and oscillators, providing reliable timing solutions.

Replacement Considerations

Direct substitutes must match the 7.6275 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics before substitution.
