18QHTF21-10.7406-OE

Overview

The 18QHTF21-10.7406-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.7406 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports enable and disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Designed as a standard crystal oscillator for timing applications

Applications

• Timing and clock signal generation in electronic devices
• Embedded systems requiring precise frequency references
• Digital circuits utilizing LVCMOS interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable pin logic levels are compatible with your controlling microcontroller or FPGA to ensure proper operation of the oscillator's start-stop functionality.

Selection Notes

Select this component when a low-profile 2.0x1.6mm footprint is required for space-constrained designs. The 1.8V operating voltage makes it suitable for modern low-power digital logic families. Consider the enable/disable feature if dynamic power saving is necessary for the application. Verify that the LVCMOS output swing meets the input requirements of the downstream clock receiver.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a small SMD package. The manufacturer specializes in quartz crystals and oscillators, providing frequency control products for industrial and consumer electronics. This specific model represents a standard XO variant optimized for compact PCB layouts.

Replacement Considerations

Direct substitutes include other 10.7406 MHz LVCMOS oscillators in 4-SMD No Lead packages with 1.8V operation. Check pinout compatibility and enable pin functionality when cross-referencing with competitors' offerings. Ensure thermal characteristics and mounting specifications match the original design constraints.
