18QHTF21-62.400-OE

Overview

The 18QHTF21-62.400-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 62.4 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of an enable/disable control pin, allowing for power management in system designs. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly processes.

Feature Summary

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

Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded microcontroller clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to guarantee proper soldering and mechanical stability during operation.

Selection Notes

Select this model when a precise 62.4 MHz reference is required with low-power consumption capabilities. The enable feature makes it suitable for battery-operated devices or systems requiring dynamic power state management. Consider the LVCMOS output swing if interfacing with high-speed digital inputs. Compare against other Mercury oscillators if different frequencies or voltage levels are needed.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of quartz crystal oscillators. The series offers various frequency options within a standardized small outline package format. Mercury Electronics is a specialized manufacturer of frequency control components, including crystals, TCXOs, and VCTCXOs, with a focus on providing reliable timing solutions for industrial and consumer electronics markets.

Replacement Considerations

Direct replacements must match the 62.4 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility for the enable function. Cross-reference with Mercury part numbers such as those in the same series but different frequencies if the exact frequency is not critical.
