18QHTF21-100.009-OE

Overview

The 18QHTF21-100.009-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 100.009 MHz and utilizes LVCMOS output logic levels. 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 with dimensions of 2.0mm x 1.6mm. The component supports a specified operating temperature range typical for commercial applications.

Feature Summary

• Integrates LVCMOS output interface for direct digital logic compatibility
• Features active enable and disable pin control for system power optimization
• Utilizes a leadless surface-mount package design for automated assembly

Applications

• High-speed data communication interfaces requiring precise clock synchronization
• Embedded systems utilizing microcontrollers or FPGAs
• Consumer electronics devices with strict size constraints

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and temperature grades. Ensure that the 1.8V supply requirement aligns with the target circuit design. Confirm package orientation markings are compatible with the intended PCB footprint. Cross-reference the part number with current availability lists from authorized distributors to prevent sourcing delays.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm footprint makes it suitable for dense board layouts. Consider the enable/disable functionality if dynamic power management is necessary. Verify that the 100.009 MHz frequency matches the system timing requirements precisely before finalizing the bill of materials.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series offers various frequencies within a standardized small outline package. Mercury has decades of experience in Taiwan's quartz industry, providing reliable timing solutions for global electronic manufacturing sectors.

Replacement Considerations

Direct substitutes include other 100.009 MHz LVCMOS oscillators in identical 4-SMD packages with matching 1.8V specifications. Verify pinout compatibility and thermal characteristics before swapping manufacturers.
