18QHTF21-31.100-OE

Oscillators Overview

The 18QHTF21-31.100-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 31.1 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. A key functional characteristic is the inclusion of an Enable/Disable control pin, allowing for power management in system designs. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm, suitable for surface-mount assembly processes.

Oscillators Feature Summary

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

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring small form factor oscillators

Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current documentation to confirm the presence of the enable pin and exact electrical characteristics. Ensure that the 1.8V supply requirement aligns with your target circuit design before procurement. Cross-reference the 4-SMD package dimensions with your PCB footprint library to guarantee mechanical compatibility.

Oscillators Selection Notes

Select this component when a precise 31.1 MHz timing source is required for LVCMOS-compatible logic families. The choice is driven by the need for a low-profile surface-mount solution with active power control capabilities. Consider the 1.8V operating voltage constraint to ensure it matches the available power rails in the application environment.

Oscillators Part Context

This part belongs to the Mercury 18QHT series of standard crystal oscillators. The series is characterized by its use of quartz resonators for stable frequency generation. Mercury Electronics specializes in frequency control products, including crystals, filters, and various oscillator types, serving the global electronics supply chain since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 31.1 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify that any replacement supports the 1.8V supply voltage and includes an enable pin if power management is critical. Check pinout compatibility to ensure seamless integration without PCB redesign.
