18QHTF21-62.914-OE

Overview

The 18QHTF21-62.914-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a fixed frequency of 62.914 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, designed for surface-mount applications requiring precise timing signals in electronic circuits.

Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Includes hardware enable and disable functionality to manage power consumption
• Utilizes a leadless SMD package design optimized for automated surface-mount assembly

Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for digital communication interfaces
• Clock distribution in consumer electronics devices

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's power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent soldering defects during assembly.

Selection Notes

Select this component when a stable 62.914 MHz reference is required with low-voltage operation. Consider the enable pin feature if dynamic power saving is necessary. Evaluate the package size constraints relative to other available oscillators in the Mercury Electronics portfolio to ensure mechanical fit within the enclosure.

Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency control solutions. The model number indicates a specific frequency variant within the 18QHTF21 family. These oscillators are designed to replace discrete crystal resonator circuits with integrated, ready-to-use clock sources for modern electronic designs.

Replacement Considerations

Direct substitutes must match the 62.914 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and electrical specifications before swapping with other manufacturers' components.
