18QHTF21-73.3337-OE

Overview

The 18QHTF21-73.3337-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 73.3337 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Provides stable clock signals via LVCMOS output interface
• Integrates enable and disable functionality for power management
• Utilizes quartz crystal technology for frequency stability

Applications

• General purpose digital circuit timing
• Embedded system clock generation
• Communication interface synchronization

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official datasheet to guarantee proper soldering and electrical connection.

Selection Notes

Select this component when a fixed frequency of 73.3337 MHz is required with low voltage operation. Consider the enable pin utility if dynamic power saving is necessary. Compare against other Mercury series oscillators if different frequencies or voltage levels are needed. Ensure compatibility with LVCMOS logic families used in the target application.

Part Context

This model belongs to the Mercury Electronics standard XO series, characterized by small form factor SMD packaging. It represents a specialized variant within their quartz oscillator lineup, tailored for applications needing specific non-standard frequencies like 73.3337 MHz while maintaining industry-standard interface protocols.

Replacement Considerations

Direct substitutes must match the 73.3337 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent performance metrics such as phase noise and stability from alternative manufacturers if cross-referencing.
