18QHTF21-4.064-OE

Oscillators Overview

The 18QHTF21-4.064-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 4.064 MHz and utilizes LVCMOS output logic levels. The device supports an enable/disable control function via the OE pin, allowing for power management flexibility in circuit designs. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for space-constrained applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output interface for digital compatibility
• Enable/Disable functionality via OE pin
• Compact 4-SMD No Lead surface mount package

Oscillators Applications

• General purpose timing circuits
• Embedded systems requiring low power consumption
• Portable electronic devices

Oscillators Procurement Notes

Verify the specific suffix 'OE' indicates the Enable/Disable feature when sourcing replacements. Confirm the package footprint matches the 2.0x1.6 mm SMD no lead specification to ensure mechanical compatibility during assembly. Cross-reference the manufacturer's latest datasheet for any updates on recommended soldering profiles or storage conditions.

Oscillators Selection Notes

Select this component when a 4.064 MHz reference clock is required with active power-down capabilities. The LVCMOS output ensures direct interfacing with standard digital logic without additional level shifting. Consider the small form factor for high-density PCB layouts where larger packages are impractical.

Oscillators Part Context

Mercury Electronic Ind. Co. Ltd specializes in frequency control products, including quartz crystals and oscillators.
