18QHTF21-86.913-OE

Overview

The 18QHTF21-86.913-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 86.913 MHz and utilizes LVCMOS output logic levels. The device requires a supply voltage of 1.8V and includes enable/disable control functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The component is designed for surface-mount assembly and supports an operating temperature range typical for commercial applications.

Feature Summary

• LVCMOS output interface for digital signal compatibility
• Integrated enable and disable control pin
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock generation in embedded systems
• Data communication interfaces requiring precise timing
• Consumer electronics with low voltage requirements

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply rail is stable and within the operational limits defined in the official datasheet. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions to prevent assembly issues. Cross-reference the part number suffix with manufacturer documentation to confirm availability and exact electrical characteristics.

Selection Notes

Select this component when a fixed 86.913 MHz clock source is required with low voltage operation. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the enable/disable feature if power conservation is a priority during idle states. Evaluate the physical size constraints of the application to ensure the 2.0x1.6mm package fits within the designated area on the printed circuit board layout.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form factor solutions. The series typically offers various frequency options within a standardized package outline. This specific model represents a high-frequency variant optimized for applications needing stable clock signals without the need for external tuning components or complex configuration circuits.

Replacement Considerations

Direct substitutes must match the 86.913 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Alternative parts from other manufacturers require careful evaluation of jitter specifications and phase noise performance to ensure system integrity is maintained.
