18QHTF21-14.487-OE

Oscillators Overview

The 18QHTF21-14.487-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 14.487 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Integrated enable and disable functionality for power management
• LVCMOS output logic compatibility
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V oscillator is required for space-constrained designs. The integrated enable pin allows for dynamic power control, making it suitable for battery-operated devices. Verify that the LVCMOS output swing meets the input threshold requirements of the downstream digital logic components.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, a manufacturer specializing in quartz crystals and oscillators since 1973. The series offers various frequencies within a small form factor. This specific model provides a fixed 14.487 MHz output, distinguishing it from other variants in the lineup that offer different frequencies or package types.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series models with identical electrical specifications but different frequencies, such as 18QHTF21-14.31818-OE, provided the frequency difference is acceptable for the application. Cross-brand replacements require matching voltage, package, and output logic.
