18QHTF21-110.540-OE

Overview

The 18QHTF21-110.540-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 110.54 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and features an enable/disable control function via the OE suffix. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports active low enable/disable control functionality
• Provides stable LVCMOS clock signals
• Compact surface-mount footprint

Applications

• High-speed digital data transmission systems
• Communication equipment requiring precise timing
• Embedded processing units

Procurement Notes

Verify that the specific part number includes the OE suffix to confirm the presence of the enable/disable pin functionality. Ensure the required supply voltage matches the 1.8V specification. Confirm the package type aligns with the PCB land pattern requirements before finalizing procurement orders.

Selection Notes

Select this component when a 1.8V supply and enable control are required for a 110.54 MHz clock source. Consider the small 2.0x1.6mm package size for space-constrained designs. Verify compatibility with LVCMOS input thresholds of downstream logic circuits.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and supply voltages. The series is characterized by small SMD packages suitable for modern electronic assemblies. This specific model provides a high-frequency option within the standard XO category.

Replacement Considerations

Direct substitutes must match the 110.54 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Check datasheets for identical pinout configurations regarding the enable signal.
