18QHTF21-110.500-OE

Overview

The 18QHTF21-110.500-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 110.5 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, suitable 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 design

Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded computing modules

Procurement Notes

Verify the specific ordering suffix matches the required frequency and voltage specifications. Confirm that the 4-SMD No Lead package dimensions align with the target PCB footprint. Ensure the LVCMOS output type is compatible with the receiving circuit's input requirements before finalizing procurement orders.

Selection Notes

Select this component when a 110.5 MHz reference clock is required with low-voltage operation. The 1.8V supply and Enable/Disable features make it suitable for battery-powered or power-sensitive designs. Consider the small form factor for space-constrained layouts.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd., a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies with standardized packages, providing reliable timing solutions for electronic systems.

Replacement Considerations

Direct substitutes must match the 110.5 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and electrical characteristics before cross-referencing other manufacturers' offerings.
