18QHTF21-81.600-OE

Overview

The 18QHTF21-81.600-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 81.6 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The unit supports surface mount mounting and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrates LVCMOS output interface for digital circuit compatibility
• Includes hardware enable and disable pin for power management
• Utilizes small form factor SMD package for space-constrained designs

Applications

• General purpose clock generation for embedded systems
• Timing reference for consumer electronics devices
• Clock source for industrial control modules

Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's official datasheet to confirm the enable/disable functionality and voltage levels. Ensure the required frequency tolerance and stability meet the target application specifications before finalizing the order. Cross-reference the package dimensions with the PCB footprint design to guarantee mechanical fit.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise timing needs. Consider the enable/disable feature if dynamic power saving is necessary during idle states. Evaluate the thermal performance within the specified -40°C to 85°C range to ensure reliability under varying environmental conditions.

Part Context

This model belongs to the Mercury Electronics XO series, designed for surface-mount applications. It represents a standard clock solution offering stable frequency generation. The product line focuses on providing reliable timing components for modern electronic assemblies requiring compact footprints and efficient power consumption profiles.

Replacement Considerations

Check for direct substitutes from Mercury Electronics such as the 18QHTF21-86.600-OE or 18QHTF21-48.900-OE if different frequencies are needed. Verify that any alternative maintains the same 1.8V supply requirement and LVCMOS output characteristics to ensure electrical compatibility.
