18QHTF21-11.046-OE

Overview

The 18QHTF21-11.046-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 11.046 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This surface-mount oscillator is suitable for timing applications requiring precise clock signals in space-constrained electronic designs.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• 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 suffix 'OE' against the manufacturer's current documentation to ensure it aligns with the required enable/disable specifications and packaging details. Confirm that the 1.8V supply voltage requirement matches the target system design before procurement. Cross-reference the part number with official Mercury Electronics datasheets to validate the exact operating temperature range and load capacitance parameters.

Selection Notes

Select this component when a low-profile 2.0x1.6mm footprint is required for 11.046 MHz timing. Ensure the host circuit supports 1.8V logic levels and LVCMOS outputs. Consider the enable pin requirement if power management during idle states is necessary. Verify that the package type meets the PCB assembly capabilities and thermal requirements of the application.

Part Context

This oscillator belongs to the Mercury Electronics 18QHTF21 series, which focuses on small-form-factor quartz oscillators. The series typically offers various frequencies and voltage options within a standardized 4-SMD no-lead package. These components are designed to replace larger through-hole or leaded packages in modern consumer and industrial electronics where board space is limited.

Replacement Considerations

Check for direct substitutes from Mercury Electronics with identical pinout and electrical characteristics. Other manufacturers offering 2.0x1.6mm LVCMOS oscillators at 11.046 MHz may require verification of pin compatibility and voltage tolerance.
