18QHTF21-124.000-OE

Overview

The 18QHTF21-124.000-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 124 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control functionality
• Designed for low voltage operation at 1.8V

Applications

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

Procurement Notes

Verify the specific suffix (OE) against official datasheets to confirm enable/disable pin configuration and voltage levels. Ensure the 4-SMD no-lead footprint matches the target PCB design. Cross-reference the 124 MHz frequency requirement with system clock specifications before procurement.

Selection Notes

Select this component when a precise 124 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V supply constraint and the need for active enable control. Evaluate the small 2.0x1.6mm package size against available board space constraints.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and voltage options within a standardized small outline package format designed for high-density electronic assemblies.

Replacement Considerations

The 18QHTF21-124.000-PD is a documented variant within the same series. Verify if the PD suffix indicates identical electrical characteristics or different packaging details before substitution.
