18QHTF21-31.660-OE

Oscillators Overview

The 18QHTF21-31.660-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 31.66 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications.

Oscillators Feature Summary

• LVCMOS output interface
• Enable/disable control capability
• Compact 4-SMD no lead package

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the manufacturer datasheet for detailed electrical characteristics to guarantee compatibility with your target application environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The enable/disable feature supports power-sensitive designs. Consider the 4-SMD package size for space-constrained layouts. Verify that the 31.66 MHz frequency meets the precise timing needs of the target digital circuit or communication interface without requiring external dividers.

Oscillators Part Context

This part belongs to Mercury's QuikXO series, which focuses on fast-delivery CMOS output clock oscillators. The series offers both standard and custom frequencies built to order. The 18QHTF21 model specifically denotes the 1.8V supply variant within this product line, distinguishing it from other voltage options like 2.5V.

Oscillators Replacement Considerations

Direct substitutes include the 25QHTF21-31.660-OE, which shares the same frequency and package but operates at 2.5V. Ensure voltage compatibility when swapping between these variants. Other frequencies in the 18QHTF21 series may serve as functional replacements if the timing requirement differs.
