18QHTF21-22.288-OE

Oscillators Overview

The 18QHTF21-22.288-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 22.288 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, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output compatibility for digital interface integration
• Integrated enable/disable pin for active power control
• Compact 4-SMD no-lead surface mount packaging

Oscillators Applications

• High-performance digital circuit timing
• Embedded system clock generation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The integrated enable function makes it suitable for battery-powered devices needing power optimization. Consider the physical size constraints of the 4-SMD package relative to available board space compared to larger through-hole alternatives.

Oscillators Part Context

This model belongs to the Mercury Electronics XO series, which specializes in quartz crystal oscillators. The manufacturer has produced frequency control products since 1973, establishing expertise in Taiwan's crystal industry. This specific part represents their capability to deliver precise timing solutions in small form factors for modern electronic designs.

Oscillators Replacement Considerations

Direct substitutes include other 22.288 MHz LVCMOS oscillators from Mercury Electronics such as the 18QHTF21-22.288-PD if pinout compatibility differs. Cross-manufacturer replacements require matching voltage, package, and electrical characteristics precisely.
