18QHTF21-1.380-OE

Overview

The 18QHTF21-1.380-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.38 MHz and utilizes an LVCMOS output signal format. The device is designed for low-power applications with a supply voltage of 1.8V. It features an Enable/Disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Feature Summary

• LVCMOS output interface
• 1.8V supply voltage operation
• Enable/Disable control functionality

Applications

• Low-power electronic devices
• Portable consumer electronics
• Embedded systems requiring precise timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before procurement. Confirm that the 1.8V logic levels are compatible with the receiving input pins. Ensure the 4-SMD footprint matches the PCB layout dimensions precisely to avoid soldering issues during assembly.

Selection Notes

Select this component when a low-frequency, low-voltage oscillator with enable control is required. Consider the 1.38 MHz frequency specifically for applications where this exact rate is necessary for clock generation or timing references. Evaluate the power consumption benefits of the enable feature if battery life is a critical design constraint.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies within the same small form factor. The 'OE' suffix likely denotes specific packaging or tape-and-reel options common in their distribution channels. It serves as a timing source for digital circuits requiring stable clock signals.

Replacement Considerations

Direct replacements must match the 1.38 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications such as jitter and stability before substituting with other manufacturers' components.
