18QHTF21-83.392-OE

Overview

The 18QHTF21-83.392-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 83.392 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 interfacing
• Integrated enable/disable functionality for power management
• Compact 4-SMD no-lead surface mount package

Applications

• General purpose clock generation in embedded systems
• Timing reference for digital signal processing circuits
• Synchronization sources for communication interfaces

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 power rails. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions specified in the official datasheet to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside LVCMOS compatibility. The integrated enable feature supports dynamic power management strategies. Consider the small form factor of the 4-SMD package for space-constrained designs. Validate that the 83.392 MHz frequency meets the exact timing needs of the application without requiring external dividers or multipliers.

Part Context

This part belongs to the 18QHTF21 series of standard XO oscillators from Mercury Electronics. The series offers various frequencies within the LVCMOS family. The -OE suffix typically denotes specific packaging or tape-and-reel options as defined by the manufacturer. These components are designed for general electronic applications requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 83.392 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and electrical specifications such as jitter and phase noise if critical. Cross-reference with other manufacturers offering equivalent SMD oscillators ensuring identical form factor and voltage levels.
