18QHTF21-24.540-OE

Oscillators Overview

The 18QHTF21-24.540-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 24.540 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features an Enable/Disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The unit supports an operating temperature range from -40°C to 85°C and maintains a frequency stability of ±50ppm.

Oscillators Feature Summary

• Integrated enable/disable functionality for efficient power management
• Compact surface-mount design suitable for space-constrained applications
• LVCMOS output interface compatible with standard digital logic

Oscillators Applications

• Embedded systems requiring precise timing references
• Consumer electronics with limited power budgets
• Industrial control modules operating in extended temperatures

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable within the specified operating range. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions exactly to prevent assembly issues. Check for any specific handling instructions regarding electrostatic discharge protection during installation.

Oscillators Selection Notes

Select this component when a low-profile oscillator with enable control is required for 24.540 MHz applications. Consider the ±50ppm stability limit to ensure it meets system synchronization needs. Evaluate the -40°C to 85°C range against environmental conditions. Compare power consumption benefits of the enable feature against alternative fixed-output oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options in a standardized small outline package. The 'OE' suffix typically denotes the inclusion of an enable pin or control feature, distinguishing it from standard continuous-output variants within the same family.

Oscillators Replacement Considerations

Direct replacements must match the 24.540 MHz frequency, 1.8V supply, and LVCMOS output. Verify pin compatibility for the enable function. Alternative packages require re-layout. Consult manufacturer cross-reference lists for verified equivalents.
