18QHTF21-12.075-OE

Overview

The 18QHTF21-12.075-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 12.075 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded system clock generation

Procurement Notes

Verify the specific ordering suffix against official Mercury Electronics documentation to ensure correct voltage and package configuration. Confirm that the LVCMOS output type matches the target circuit requirements. Cross-reference the enable/disable feature availability with the latest datasheet specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS signaling. The enable/disable pin allows for power management integration. Ensure the 4-SMD footprint fits the PCB layout constraints. Validate the 12.075 MHz frequency requirement against system clock needs.

Part Context

This part belongs to the Mercury Electronics XO series, which provides stable quartz-based oscillators. The manufacturer specializes in frequency control products including crystals and oscillators. This specific model represents a standard output variant within their portfolio of surface-mount timing devices.

Replacement Considerations

Direct substitutes must match the 12.075 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify electrical parameters and pinout compatibility with alternative manufacturers offering similar surface-mount oscillators.
