18QHTF21-3.801562-OE

Oscillators Overview

The 18QHTF21-3.801562-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 3.801562 MHz and utilizes an LVCMOS output interface. The device requires a 1.8V supply voltage and includes enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package designed for surface-mount applications. The component supports operation within a temperature range of -40°C to 85°C.

Oscillators Feature Summary

• LVCMOS output signal compatibility
• Integrated enable and disable control function
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring precise frequency standards

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 3.801562 MHz specification. Confirm the 1.8V supply requirement aligns with the target system design. Ensure the LVCMOS output logic levels are compatible with downstream components. Check the operating temperature range suitability for the intended environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is available and LVCMOS outputs are required. Consider the small 4-SMD footprint for space-constrained PCB layouts. Evaluate the need for active enable/disable control versus always-on oscillators. Verify that the standard XO stability meets the system timing requirements.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics and packaging. The 'OE' suffix typically denotes the presence of an output enable pin. Mercury Electronics specializes in quartz frequency control products including crystals and oscillators.

Oscillators Replacement Considerations

Direct replacements must match the 3.801562 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal specifications. Cross-reference with other Mercury 18QHTF21 variants if frequency adjustments are permissible.
