18QHTF21-28.6364-OE

Oscillators Overview

The 18QHTF21-28.6364-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 28.6364 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable and disable functionality for power management
• Surface-mount construction in a leadless SMD package

Oscillators Applications

• General clock signal generation
• Digital circuit timing references
• Embedded system synchronization

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 28.6364 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package dimensions fit the PCB footprint requirements. Check for any specific ordering suffixes that may indicate variations in tolerance or temperature range.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for standard digital logic families. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the enable pin feature supports the system's power sequencing needs.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of standard XO oscillators. Similar models in this series include variants with different frequencies such as 44.200 MHz and 34.4064 MHz, all sharing the same 1.8V LVCMOS output and 4-SMD package configuration. The series is characterized by its compact size and enable/disable capability.

Oscillators Replacement Considerations

Direct substitutes within the same series include 18QHTF21-44.200-OE, 18QHTF21-34.4064-OE, and 18QHTF21-67.563-OE, provided the frequency difference is acceptable. Other Mercury oscillators like H21 or SWO series may offer similar form factors but require verification of electrical parameters.
