18QHTF21-13.40155-OE

Overview

The 18QHTF21-13.40155-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.40155 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable functionality for power control
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics and reliability data to ensure component suitability for your application environment.

Selection Notes

Select this component when a stable 13.40155 MHz reference is required with low voltage operation. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. Consider the enable pin utility if power conservation during idle states is a design priority. Evaluate the small form factor benefits for space-constrained portable or dense electronic assemblies.
