18QHTF21-15.900-OE

Oscillators Overview

The 18QHTF21-15.900-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 15.9 MHz. It utilizes an LVCMOS output interface and functions with a supply voltage of 1.8V. The component features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrates LVCMOS output interface for digital logic compatibility
• Supports active enable and disable control states
• Designed for low-voltage operation at 1.8V
• Utilizes leadless SMD packaging for board space efficiency

Oscillators Applications

• General-purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards
• Industrial control modules

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm the Enable/Disable functionality. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD No Lead package dimensions match the PCB footprint specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this model when a 15.9 MHz reference is required with low-power standby capabilities. The LVCMOS output suits direct interfacing with standard logic families. Consider the 1.8V operating voltage constraint relative to other available voltage options within the same series if higher voltage tolerance is needed.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form-factor timing solutions. The series typically includes variants with different frequencies and control pin configurations, such as Power Down (PD) or Enable/Disable (OE), sharing similar physical package constraints.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-15.900-PD, which offers identical frequency and package but utilizes a Power Down control mechanism instead of Enable/Disable. Verify functional equivalence regarding control logic polarity before swapping.
