18QHTF21-3.883-OE

Oscillators Overview

The 18QHTF21-3.883-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a frequency of 3.883 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features enable/disable control functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes enable/disable control pin for power management
• Operates on a single 1.8V supply voltage

Oscillators Applications

• General-purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package dimensions fit the PCB footprint constraints. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS outputs. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the 3.883 MHz frequency specifically for applications needing this exact timing reference rather than standard frequencies. Evaluate the small form factor against available board space limitations.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which specializes in quartz crystals and oscillators. The company has been manufacturing frequency control products since 1973. This series typically offers standard XO options with various frequency choices and voltage levels, catering to diverse electronic timing needs.

Oscillators Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 3.883 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions precisely.
