18QHTF21-32.775-OE

Oscillators Overview

The 18QHTF21-32.775-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 32.775 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• General clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 32.775 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package dimensions fit the PCB footprint constraints. Check for any specific operating temperature range requirements against the datasheet.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS interface compatibility. The enable/disable feature makes it suitable for battery-powered devices needing power conservation. Consider the small form factor of the 4-SMD package for space-constrained layouts.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount oscillators. The series offers various frequencies and voltage options. Mercury Electronics is a established manufacturer of frequency control products, including crystals and oscillators, with a long history in the industry.

Oscillators Replacement Considerations

Direct substitutes include other 32.768 kHz or 32.775 MHz oscillators from different manufacturers if frequency tolerance allows. Verify pinout compatibility for the 4-SMD package. Ensure equivalent electrical characteristics such as load capacitance and drive level are matched.
