18QHTF21-124.913-OE

Overview

The 18QHTF21-124.913-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 124.913 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an Enable/Disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features active enable/disable control functionality
• Utilizes a leadless surface-mount package design

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

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 PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly errors during manufacturing.

Selection Notes

Select this component when a precise 124.913 MHz reference is required for low-voltage digital circuits. Consider the LVCMOS output swing levels to ensure compatibility with downstream logic inputs. Evaluate the thermal performance and operating temperature range to guarantee stability under the intended environmental conditions.

Part Context

This oscillator belongs to the Mercury Electronics XO series, which provides standard frequency solutions. The model number indicates a 1.8V operation and OE pin configuration. It serves as a primary clock source for electronic devices requiring stable timing signals without differential outputs.

Replacement Considerations

Direct substitutes must match the 124.913 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify equivalent electrical parameters from other manufacturers if cross-sourcing.
