12.94412

Overview

The Geyer Electronic America, Inc. model 12.94412 is a standard crystal oscillator (XO) designed for surface-mount applications. It utilizes a 4-SMD, No Lead package form factor to facilitate automated assembly processes. The device operates with CMOS and TTL logic compatibility and supports a supply voltage of 3.3V. A key functional characteristic is the inclusion of a tri-state output enable feature, allowing for bus isolation when not in use. The unit maintains a frequency stability of 100 ppm across its operational range. It is rated for an operating temperature span from -40°C to +85°C, ensuring reliability in demanding industrial environments.

Feature Summary

• Surface-mount construction with a compact 4-SMD, No Lead package design
• CMOS and TTL compatible logic levels for broad interface integration
• Tri-state output capability for effective signal control and bus management
• Industrial-grade thermal rating supporting operation from -40°C to +85°C

Applications

• General-purpose digital clock generation in embedded systems
• Timing reference sources for microcontroller-based circuits
• Communication interface synchronization modules
• Industrial control system timing components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package variant and tolerance specifications. Confirm that the required frequency stability of 100 ppm aligns with the target application's timing requirements. Ensure the 3.3V supply voltage matches the host circuit's power domain. Validate the operating temperature range against the environmental conditions of the final product deployment. Cross-reference the pinout diagram with the PCB footprint design to guarantee mechanical and electrical compatibility during assembly.

Selection Notes

Select this component when a surface-mount oscillator with tri-state output functionality is required for 3.3V logic systems. The 100 ppm stability specification suits applications where moderate timing precision is sufficient. Consider the 4-SMD, No Lead package for reflow soldering processes. Evaluate the -40°C to +85°C temperature range against the intended operating environment. This part is appropriate for designs prioritizing compact board space and standardized logic interfaces over ultra-high precision or lower power consumption alternatives.
