18QHTF21-13.333333-OE

Overview

The 18QHTF21-13.333333-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.333333 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function 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 control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation
• Digital system timing references
• Embedded electronics timing circuits

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent component damage during operation.

Selection Notes

Select this component when a precise 13.333333 MHz reference is required with low-voltage operation. The LVCMOS output ensures direct interfacing with standard digital logic families without additional level shifting. The enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs requiring periodic clock activation.

Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount oscillators. The series typically offers various frequencies within a small form factor. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though exact details require datasheet verification. This model represents a standard fixed-frequency solution within their quartz-based product line.

Replacement Considerations

Direct substitutes must match the 13.333333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify electrical parameters such as phase noise and jitter specifications if they are critical to the application. Check for equivalent enable/disable functionality to ensure seamless integration into existing designs.
