18QHTF21-100.040041-OE

Overview

The 18QHTF21-100.040041-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 100.040041 MHz and utilizes LVCMOS output logic. 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. This component is engineered for applications requiring precise timing signals in low-voltage digital systems.

Feature Summary

• Supports enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital compatibility
• Compact 4-SMD no-lead surface mount package

Applications

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

Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application design before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent assembly issues. Cross-reference the manufacturer datasheet for detailed electrical specifications and operating temperature ranges.

Selection Notes

Select this component when a 100.040041 MHz clock signal is required in space-constrained designs. The enable pin allows for dynamic power control, making it suitable for battery-operated devices. Ensure the host circuit supports LVCMOS logic levels. Consider the operating temperature range if the environment exceeds standard commercial limits. Verify compatibility with the 1.8V power supply infrastructure.

Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and package sizes optimized for modern electronics. The 'OE' suffix indicates the presence of an output enable pin, distinguishing it from standard continuous-output variants. These oscillators are designed to replace discrete crystal and amplifier solutions in compact form factors.

Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical frequency and package but different control features. Verify that alternative sources maintain the same LVCMOS output characteristics and 1.8V supply requirements. Check for equivalent thermal performance and stability metrics if replacing with components from different manufacturers.
