18QHTF21-12.96009-OE

Overview

The 18QHTF21-12.96009-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.96009 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package designed for surface mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable and disable control functionality
• Utilizes a leadless SMD package for automated assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 1.8V operation
• Embedded devices utilizing LVCMOS compatible interfaces

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 mounting issues during assembly.

Selection Notes

Select this component when a precise 12.96009 MHz timing source is required within a low-voltage 1.8V environment. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable pin requirement if power management or clock gating is necessary for the application.

Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent 1.8V operation and LVCMOS outputs. The model number indicates the specific frequency variant within this standardized product line.

Replacement Considerations

Direct substitutes must match the 12.96009 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent electrical specifications including phase noise and jitter if critical performance is required.
