12.94619

Overview

The Geyer Electronic America, Inc. part number 12.94619 is a ceramic surface-mount oscillator operating at a frequency of 18.432 MHz. It utilizes a standard XO configuration with a 3.3V supply voltage and features an enable/disable control function. The component is housed in a compact 4-SMD, No Lead package, designed for integration into electronic circuits requiring precise timing signals.

Feature Summary

• Offers stable frequency generation using ceramic resonator technology
• Includes hardware enable and disable functionality for power management
• Designed for surface-mount assembly to facilitate automated manufacturing processes

Applications

• General-purpose timing reference in consumer electronics
• Clock source for microcontroller-based systems
• Synchronization in communication interface circuits

Procurement Notes

Verify the specific manufacturer datasheet for electrical tolerances and thermal characteristics before finalizing design integration. Confirm that the 3.3V logic levels align with your system's I/O requirements. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any Class III life-support device restrictions if used in critical applications.

Selection Notes

Select this component when a fixed 18.432 MHz output is required without programmability. The enable pin allows for dynamic power control, making it suitable for battery-operated devices. Consider the ceramic construction for cost-effectiveness compared to quartz alternatives where extreme stability is not mandatory.
