18QHTF21-23.804-OE

Oscillators Overview

The 18QHTF21-23.804-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 23.804 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features enable/disable functionality. It offers a frequency stability of ±50ppm and functions within an operating temperature range of -40°C to +85°C. The component is housed in a compact 4-SMD, No Lead package.

Oscillators Feature Summary

• Supports enable and disable control for power management
• Provides LVCMOS output signal compatibility
• Operates on a single 1.8V power supply

Oscillators Applications

• Embedded systems requiring precise clock timing
• Consumer electronics with low power constraints
• Industrial control modules operating in varied temperatures

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail can maintain stable voltage under all load conditions. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to prevent assembly issues.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS interface compatibility. Consider the ±50ppm stability specification for applications needing moderate precision. The wide temperature range makes it suitable for environments subject to thermal fluctuations without requiring additional heating or cooling mechanisms.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically includes various frequencies optimized for digital circuits. The 'OE' suffix often denotes specific packaging or tape-and-reel configurations, though verification against the manufacturer's current documentation is recommended for exact handling specifications.

Oscillators Replacement Considerations

Direct substitutes must match the 23.804 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar SMD oscillators if Mercury Electronics availability is limited.
