18QHTF21-4.0096-OE

Oscillators Overview

The 18QHTF21-4.0096-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 4.0096 MHz and utilizes LVCMOS output logic. 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, 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
• Digital circuit timing references
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application 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 provided 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 signaling levels. The enable/disable feature makes it suitable for systems requiring power conservation or controlled clock activation. Consider the small form factor of the 4-SMD package for space-constrained designs where traditional leaded packages are unsuitable.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronic. The series offers various frequency options within a standardized small outline package. Mercury Electronic has extensive experience in frequency control products, including crystals and oscillators, providing a range of solutions for different timing needs across consumer and industrial electronics.

Oscillators Replacement Considerations

Direct replacements must match the 4.0096 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as jitter and phase noise if critical. Alternative parts from other manufacturers require careful evaluation of thermal and environmental operating ranges.
