18QHTF21-11.05992-OE

Overview

The 18QHTF21-11.05992-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 11.05992 MHz and utilizes LVCMOS output logic. The device supports an enable/disable control function and requires a supply voltage of 1.8V. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports active low or high enable/disable control functionality
• Utilizes LVCMOS output logic for digital interface compatibility
• Housed in a leadless 4-SMD surface-mount package

Applications

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

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 power management architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the OE suffix to confirm any specific ordering or packaging variations defined by the manufacturer.

Selection Notes

Select this component when a stable 11.05992 MHz reference is required for LVCMOS-compatible circuits. Consider the 1.8V operating voltage and enable pin availability as key selection criteria. Evaluate the 4-SMD package size for space-constrained designs. Compare performance against other Mercury Electronics oscillators if different frequencies or logic families are needed.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a consistent 4-SMD form factor. These components are designed for general-purpose timing applications where moderate stability and low cost are prioritized over high-performance temperature compensation.

Replacement Considerations

Direct substitutes must match the 11.05992 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package. Verify pinout compatibility and enable logic polarity. Check datasheets for equivalent parts from Mercury Electronics or other manufacturers offering identical electrical characteristics and mechanical dimensions.
