18QHTF21-13.5168-OE

Overview

The 18QHTF21-13.5168-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 13.5168 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Enable/Disable control function. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable control functionality
• Utilizes low-voltage 1.8V power supply operation
• Employes leadless SMD packaging for automated assembly

Applications

• General-purpose digital timing circuits
• Embedded system clock generation
• Communication module synchronization
• Microcontroller peripheral interfaces

Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm the presence of the enable pin and exact electrical characteristics. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm the 4-SMD no-lead footprint dimensions match the PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V oscillator is required for space-constrained designs. The LVCMOS output is appropriate for standard digital logic families. Consider the enable feature if power management or signal gating is necessary. Verify that the 13.5168 MHz frequency meets the system timing requirements compared to other available options.

Part Context

This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies and voltage levels. The 18 prefix indicates the 1.8V operating voltage range. This specific model provides a fixed frequency solution for applications needing stable clock sources without external tuning components.

Replacement Considerations

Direct substitutes must match the 13.5168 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Check Mercury Electronics documentation for cross-reference lists. Other manufacturers may offer equivalent parts but require verification of pinout and electrical parameters.
