18QHTF21-2.488-OE

Oscillators Overview

The 18QHTF21-2.488-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 2.488 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Enable/Disable control functionality for power management
• Compact 4-SMD No Lead surface-mount package design

Oscillators Applications

• General clock signal generation in embedded systems
• Timing reference for low-frequency digital circuits
• Consumer electronics requiring precise timekeeping

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 2.488 MHz operation. Confirm the 1.8V supply requirement aligns with the target system voltage. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check the 4-SMD No Lead package dimensions against the PCB footprint to guarantee proper assembly and soldering integrity.

Oscillators Selection Notes

Select this component when a stable 2.488 MHz clock source is required for LVCMOS-compatible circuitry. The 1.8V operating voltage makes it suitable for modern low-power designs. The enable/disable feature allows for dynamic power saving. Consider the -40°C to 85°C operating range for industrial or commercial environments where temperature stability is necessary.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series includes various frequencies such as 6.300 MHz, 7.9488 MHz, and 65.488 MHz, all sharing similar package and electrical characteristics. The manufacturer has been active in the frequency-control industry since 1973.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants like 18QHTF21-6.300-OE or 18QHTF21-7.9488-OE if frequency adjustment is acceptable. Cross-brand replacements must match the 4-SMD No Lead package, 1.8V supply, and LVCMOS output type.
