18QHTF21-14.746-OE

Oscillators Overview

The 18QHTF21-14.746-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 14.746 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications. This component serves as a precise clock source for digital circuits requiring stable timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for direct interface with digital components
• Features integrated enable and disable functionality for power control
• Utilizes a leadless SMD package for automated surface-mount assembly

Oscillators Applications

• Digital system clock generation
• Timing reference for microprocessors
• Synchronization in communication interfaces

Oscillators Procurement Notes

Verify the specific suffix OE against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the 1.8V supply requirement aligns with the target circuit design. Confirm that the LVCMOS output swing matches the input thresholds of the receiving logic devices to guarantee signal integrity.

Oscillators Selection Notes

Select this oscillator when a 14.746 MHz frequency is required for synchronous digital systems. The 1.8V operating voltage makes it suitable for low-power portable electronics. The enable/disable feature allows for dynamic power management. Consider the 4-SMD package size for PCB space constraints and manufacturing compatibility.

Oscillators Part Context

This part belongs to the Mercury Electronics XO series, which provides standard frequency oscillators. The brand has specialized in quartz frequency control products since 1973. The 18QHTF21 model line typically offers various frequencies within a consistent package footprint, allowing for design flexibility across different product variants while maintaining mechanical interchangeability.

Oscillators Replacement Considerations

Direct substitutes include other 14.746 MHz LVCMOS oscillators in a 4-SMD No Lead package with 1.8V operation. Verify that alternative parts match the enable/disable pin configuration and output drive strength.
