12.94212

Overview

The Geyer Electronic America, Inc. model 12.94212 is a standard CMOS/TTL crystal oscillator (XO) operating at a frequency of 12.288 MHz. It features a 5V enable/disable control function and utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm. The device supports surface-mount installation and is designed for applications requiring precise timing signals with low power consumption.

Feature Summary

• Integrated enable/disable functionality for power management
• CMOS/TTL compatible output levels
• Compact surface-mount footprint

Applications

• Digital clock circuits
• Microcontroller system clocks
• Communication interface timing

Procurement Notes

Verify the specific voltage tolerance and load capacitance requirements against the official datasheet before integration. Confirm that the 5V enable signal logic levels match the controlling microcontroller outputs to ensure reliable operation. Check for any specific reflow soldering profile recommendations provided by the manufacturer to maintain component integrity during assembly.

Selection Notes

Select this component when a fixed 12.288 MHz frequency is required with active power control capabilities. Ensure the application environment supports the specified operating temperature range and that the 4-SMD package fits within the available PCB real estate constraints.

Part Context

This oscillator belongs to the standard XO series from Geyer Electronic, designed for general-purpose timing applications. It replaces discrete crystal and amplifier solutions by integrating the necessary circuitry into a single compact package, simplifying design complexity and reducing board space usage.

Replacement Considerations

Direct substitutes must match the 12.288 MHz frequency, 5V supply, and CMOS/TTL output type. Verify pin compatibility and thermal characteristics before swapping with other manufacturers' offerings.
