18QHTF21-12.424-OE

Overview

The 18QHTF21-12.424-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 12.424 MHz and utilizes an LVCMOS output interface. The device functions with a supply voltage of 1.8V and includes enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated enable and disable control functionality
• Compact 4-SMD surface-mount package design

Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• 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 footprint matches the PCB layout constraints. Cross-reference the manufacturer datasheet for precise electrical characteristics to guarantee reliable operation under intended environmental conditions.

Selection Notes

Select this component when a precise 12.424 MHz timing source is required for low-power applications. The LVCMOS output suits standard logic families operating at 1.8V. Consider the enable/disable feature if power management or clock gating is necessary. The small form factor is suitable for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'OE' suffix typically denotes specific ordering or configuration details defined by the manufacturer. This model provides a stable clock solution within the broader portfolio of frequency control products.

Replacement Considerations

Direct substitutes must match the 12.424 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications such as jitter and phase noise. Consult the manufacturer's official substitution list for validated alternatives.
