18QHTF21-10.000123-OE

Overview

The 18QHTF21-10.000123-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 10.000123 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, no-lead package suitable for surface-mount applications.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Standard crystal resonator base construction

Applications

• General clock signal generation in electronic circuits
• Digital system timing references
• Embedded device clock sources

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications before ordering.

Selection Notes

Select this component when a precise 10.000123 MHz clock source is required with low-voltage operation. The LVCMOS output is suitable for standard digital logic families. Consider the enable/disable feature if power management or clock gating is necessary for the application.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent 4-SMD packaging. The 'OE' suffix typically denotes specific packaging or tape-and-reel options as defined by the manufacturer's catalog structure.

Replacement Considerations

Direct substitutes must match the 10.000123 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics such as current consumption and stability before cross-referencing.
