18QHTF21-10.6656-OE

Overview

The 18QHTF21-10.6656-OE is a quartz crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a nominal frequency of 10.6656 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.

Feature Summary

• LVCMOS output logic compatibility
• Integrated enable/disable functionality
• Compact 4-SMD no lead package design

Applications

• Precision timing circuits
• High-performance digital systems

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no lead footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a stable 10.6656 MHz reference is required with low-voltage operation. The LVCMOS interface ensures direct compatibility with standard digital logic families. Consider the enable pin feature if dynamic power saving is necessary. The small form factor suits space-constrained designs where traditional through-hole oscillators cannot fit.
