18QHTF21-8.100-OE

Overview

The 18QHTF21-8.100-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 8.100 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. It is housed in a compact 4-SMD, No Lead package designed for surface-mount applications.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Features integrated enable and disable control functionality
• Designed for low-voltage operation at 1.8V

Applications

• General clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct frequency and voltage specifications. Confirm that the required operating temperature range aligns with your application environment. Ensure the 4-SMD no-lead package dimensions are compatible with your PCB footprint design before finalizing procurement.

Selection Notes

Select this component when an 8.100 MHz clock source is required with LVCMOS outputs. Consider the 1.8V supply requirement and the need for enable/disable control features. Evaluate the physical size constraints of the 4-SMD package against available board space. Compare performance requirements against other frequencies within the same series if different timing is needed.

Part Context

This oscillator belongs to the Mercury Electronics 18QHTF21 series, which offers various standard frequencies. The series provides SMD solutions for timing applications. Similar models include variants like 18QHTF21-96.768-OE and 18QHTF21-65.300-OE, differing primarily in output frequency while maintaining similar package and electrical characteristics.

Replacement Considerations

Direct substitutes must match the 8.100 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with Mercury Electronics datasheets for equivalent part numbers.
