18QHTF21-71.500-OE

Overview

The 18QHTF21-71.500-OE is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 71.5 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes enable/disable control capabilities. 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 for standard digital interface compatibility
• Integrated enable and disable functionality for power management
• Compact 4-SMD no-lead surface mount package design

Applications

• General clock signal generation in electronic circuits
• Timing reference for digital systems requiring 71.5 MHz
• Embedded devices utilizing LVCMOS compatible interfaces

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this component when a 71.5 MHz LVCMOS clock source is required with low voltage operation. Consider the enable/disable feature if dynamic power control is necessary for the application. Evaluate the physical dimensions of the 4-SMD package against available board space constraints to ensure compatibility with existing manufacturing equipment and assembly workflows.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies with LVCMOS outputs and 1.8V operation. The suffix -OE indicates specific ordering or packaging variations within the manufacturer's product line, distinguishing it from other variants in the same family.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. Direct replacement requires matching the 71.5 MHz frequency, LVCMOS output type, 1.8V supply voltage, and 4-SMD package dimensions exactly to maintain circuit functionality.
