18QHTF21-31.980-OE

Oscillators Overview

The 18QHTF21-31.980-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 31.98 MHz and utilizes LVCMOS output logic levels. The device supports an active enable/disable control function and is powered by a single 1.8V supply voltage. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• Supports active enable and disable control functionality
• Utilizes LVCMOS output signal compatibility
• Operates on a low-voltage 1.8V power supply

Oscillators Applications

• Embedded systems requiring precise clock timing
• Portable electronic devices utilizing low-power components
• Communication modules needing stable frequency references

Oscillators Procurement Notes

Verify the specific suffix OE against official Mercury Electronics documentation to confirm pinout and electrical characteristics. Ensure the target application circuit provides a stable 1.8V supply rail compatible with LVCMOS thresholds. Confirm that the 4-SMD no-lead footprint matches the PCB land pattern design specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile 2.0x1.6 mm oscillator is required for space-constrained designs. The 1.8V operation makes it suitable for modern low-power digital logic families. Consider the enable/disable feature if power management during idle states is necessary for the system architecture.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, which includes various frequencies and packages. The 18QHTF21 series specifically targets applications requiring small form factors. Mercury Electronics has established itself as a manufacturer of quartz-based frequency control products since 1973.

Oscillators Replacement Considerations

Direct substitutes may include other 31.98 MHz LVCMOS oscillators in 4-SMD no-lead packages from different manufacturers. Verify voltage tolerance and enable pin logic polarity before swapping. Cross-reference datasheets for thermal and mechanical compliance.
