18QHTF21-16.664-OE

Oscillators Overview

The 18QHTF21-16.664-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.664 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, no lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• General purpose clock generation
• Digital signal processing systems
• Embedded controller timing sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations required by your application environment.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator with enable functionality is required. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the 1.8V supply constraint during power budgeting. The small form factor makes it appropriate for space-constrained designs where traditional through-hole oscillators cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-footprint crystal oscillators. The series typically offers various frequencies within a standardized package. The 'OE' suffix likely denotes the presence of an output enable feature, distinguishing it from basic continuous-output variants in the same family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.664 MHz frequency, LVCMOS output type, 1.8V supply, and 4-SMD package dimensions. Verify that alternative vendors provide equivalent enable/disable functionality. Cross-reference pin assignments to ensure compatibility without PCB redesign.
