18QHTF21-16.3677-OE

Oscillators Overview

The 18QHTF21-16.3677-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 16.3677 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning with a supply voltage of 1.8V. It features an enable/disable control pin for power management flexibility. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable/disable functionality for power optimization
• Compact surface-mount form factor

Oscillators Applications

• General-purpose clock generation in embedded systems
• Synchronization circuits requiring stable timing references
• Low-voltage digital logic interfacing

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar variants in the series.

Oscillators Selection Notes

Select this model when a precise 16.3677 MHz reference is required for LVCMOS-compatible devices. Consider the enable pin utility if dynamic power saving is necessary. Evaluate the thermal and mechanical stability needs of the application to ensure the standard XO performance meets long-term reliability standards compared to TCXO alternatives.

Oscillators Part Context

This component belongs to Mercury Electronics' line of surface-mount crystal oscillators. The '18QHTF21' prefix typically denotes a specific series of low-profile, leadless packages designed for high-density electronics. The '-OE' suffix indicates the inclusion of an enable/disable control feature, distinguishing it from basic continuous-output models within the same physical footprint family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.3677 MHz frequency, 1.8V operating voltage, LVCMOS output type, and 4-SMD package dimensions. Verify that any replacement part includes the enable/disable function if power control is critical to the design.
