18QHTF21-9.984-OE

Overview

The 18QHTF21-9.984-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 9.984 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, no lead package suitable for surface mount applications.

Feature Summary

• LVCMOS output interface
• Enable/Disable control functionality
• RoHS compliant construction

Applications

• General purpose timing circuits
• Embedded systems clock generation
• Consumer electronics timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints to guarantee proper assembly and electrical connectivity.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable pin allows for dynamic power saving in battery-operated devices. Consider the 4-SMD form factor for space-constrained designs requiring reliable surface mount integration without through-hole processing.

Part Context

This part belongs to the QHTF series of surface mount oscillators from Mercury Electronics. The series typically offers various frequencies within a standardized small outline package. The OE suffix indicates specific ordering or packaging variations defined by the manufacturer for distribution channels.

Replacement Considerations

Direct substitutes must match the 9.984 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent enable/disable functionality and RoHS compliance. Cross-reference with other manufacturers offering similar SMD oscillators if availability is constrained.
