18QHTF21-32.571-OE

Oscillators Overview

The 18QHTF21-32.571-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 32.571 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an Output Enable/Disable function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable control functionality
• Compact surface-mount package design

Oscillators Applications

• Microcontroller clock sources
• Digital signal processing systems
• Communication equipment timing circuits

Oscillators Procurement Notes

Verify the specific suffix 'OE' to confirm the 1.8V supply voltage and enable/disable feature set. Ensure the package type matches the required 4-SMD, No Lead footprint. Cross-reference the frequency tolerance specifications against system requirements before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a 32.571 MHz clock source is required with low voltage operation. The enable pin allows for dynamic power management in battery-operated devices. Compare against the 'PD' variant if standby power-down functionality is preferred over simple enable/disable control.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 18QHTF21 model specifically denotes the 2.0x1.6 mm form factor, distinguishing it from larger packages in the same product line.

Oscillators Replacement Considerations

The 18QHTF21-32.571-PD is a related variant offering power-down functionality instead of enable/disable. Verify that the change in control logic does not impact the host circuit design before substituting.
