18QHTF21-14.000-OE

Overview

The 18QHTF21-14.000-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an active high enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface for digital compatibility
• Active high enable/disable pin for power control
• 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 tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the enable/disable pin logic level matches your controller's output capabilities to guarantee proper operation.

Selection Notes

Select this component when a low-voltage 1.8V LVCMOS oscillator is required. The choice is driven by the need for a small 2.0x1.6 mm footprint and the necessity for an enable pin to manage power consumption during idle states. Verify that the 14 MHz frequency meets the target application's timing needs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized small outline package. The series provides options for different supply voltages and output types, allowing designers to select components based on specific power and interface constraints within compact electronic designs.

Replacement Considerations

Check for direct substitutes such as the 18QHTF21-13.558-OE or other variants in the same series if frequency adjustments are permissible. Ensure any replacement maintains the 1.8V supply requirement and LVCMOS output characteristics to preserve circuit compatibility.
