18QHTF21-13.508-OE

Overview

The 18QHTF21-13.508-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 13.508 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V. The component features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Timing and clock signal generation in electronic devices
• Digital circuit synchronization
• Embedded system clock sources

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 4-SMD no-lead footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable feature makes it suitable for power-sensitive designs. Consider the physical dimensions of the 4-SMD package to ensure adequate space on the printed circuit board relative to other components.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various frequencies such as 4.31818 MHz and 59.2 MHz, all sharing similar package and electrical characteristics. Mercury Electronics has been manufacturing these components since 1973, establishing a history in the crystal industry.

Replacement Considerations

Direct substitutes within the same series include models like 18QHTF21-4.31818-OE or 18QHTF21-59.200-OE if frequency differences are acceptable. Verify pinout compatibility and voltage levels when considering alternative manufacturers' oscillators with similar LVCMOS outputs.
