18QHTF21-108.480-OE

Overview

The 18QHTF21-108.480-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 108.48 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function. 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

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific frequency suffix matches the required 108.48 MHz specification. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout. Check for any specific operating temperature range requirements against the datasheet.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor for space-constrained designs. Verify that the 108.48 MHz frequency meets the system's clocking needs.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD no-lead package. The series supports LVCMOS outputs and 1.8V operation, providing a consistent platform for different timing requirements across multiple product lines.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with identical package and electrical characteristics but different frequency suffixes, such as 18QHTF21-108.000-OE or 18QHTF21-109.000-OE, provided the frequency difference is acceptable for the application.
