18QHTF21-31.996875-OE

Oscillators Overview

The 18QHTF21-31.996875-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 31.996875 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features an Enable/Disable control function 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

• Supports Enable/Disable functionality for active power control
• Utilizes LVCMOS output logic for digital interface compatibility
• Operates on a 1.8V single supply voltage

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for digital signal processing circuits
• Communication module synchronization

Oscillators Procurement Notes

Verify the specific suffix 'OE' corresponds to the Enable/Disable feature when ordering. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Ensure the 4-SMD No Lead footprint matches the PCB layout design specifications before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise frequency stability. The Enable/Disable pin allows for dynamic power saving in battery-operated devices. Consider the small form factor suitable for dense circuit board layouts compared to larger through-hole alternatives.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF series of surface-mount oscillators. The series typically offers various frequencies and supply voltages. The 'O' suffix often denotes specific operational characteristics like enable pins, distinguishing it from standard continuous-output variants within the same family.

Oscillators Replacement Considerations

The 18QHTF21-31.996875-PD is a related variant offering Standby (Power Down) functionality instead of simple Enable/Disable. Verify if the standby mode meets power requirements better than the OE version. Both share similar electrical parameters and package types.
