18QHTF21-10.140-OE

Overview

The 18QHTF21-10.140-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.14 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control pin for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Features an enable/disable pin for active power control
• Utilizes a surface-mount package suitable for automated assembly

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded system clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions to prevent soldering issues during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 10.14 MHz reference. The integrated enable function makes it suitable for battery-powered or power-sensitive applications where standby current reduction is necessary. Consider the small form factor for space-constrained board layouts.

Part Context

This part belongs to the Mercury Electronics XO series, designed for general electronic applications. The manufacturer specializes in quartz crystals and oscillators, offering various frequency options within the same package family. The 'OE' suffix typically denotes the presence of an output enable feature.

Replacement Considerations

Direct replacements must match the 10.14 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the enable pin configuration, to ensure seamless integration without circuit modification.
