18QHTF21-8.388608-OE

Overview

The 18QHTF21-8.388608-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 8.388608 MHz and utilizes LVCMOS output logic. 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, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features an enable/disable pin for active power management control
• Utilizes a leadless 4-SMD surface-mount package for board space efficiency

Applications

• Embedded system clock generation
• Consumer electronics timing references
• Industrial control unit synchronization

Procurement Notes

Verify the specific frequency suffix matches the required 8.388608 MHz specification during procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint is compatible with the PCB layout. Cross-reference the manufacturer datasheet for absolute maximum ratings before integration to prevent component damage.

Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for standard logic families. Consider the enable/disable functionality if power conservation is a priority. The small form factor makes it appropriate for dense circuit boards where space is limited compared to larger oscillator packages.

Part Context

This model belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series typically offers various frequency options within a standardized physical footprint. Mercury Electronics specializes in frequency control products, providing quartz-based solutions for diverse electronic industries. This specific part represents a fixed-frequency variant within that product line.

Replacement Considerations

Direct substitutes must match the 8.388608 MHz frequency, 1.8V supply, and LVCMOS output type. Verify that any replacement maintains the 4-SMD no-lead package dimensions for mechanical compatibility. Check if the alternative component supports the same enable/disable control scheme. Consult official manufacturer cross-reference lists for verified equivalent part numbers.
