18QHTF21-37.95762-OE

Oscillators Overview

The 18QHTF21-37.95762-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 37.95762 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes an enable/disable control function. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

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

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Digital communication interfaces

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS outputs. The enable/disable feature allows for power management in battery-operated devices. Consider the small form factor of the 4-SMD package for space-constrained designs. Verify that the operating temperature range meets the environmental conditions of the intended application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The suffix OE typically denotes specific packaging or tape-and-reel configurations as defined by the manufacturer. This model provides a fixed frequency solution for timing applications without the need for external tuning components.

Oscillators Replacement Considerations

Direct replacements must match the 37.95762 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Cross-reference pinouts and electrical characteristics with alternative manufacturers' datasheets to ensure functional compatibility. Verify that any substitute part maintains the same enable/disable control logic and physical dimensions.
