12.94679

Overview

The Geyer Electronic America, Inc. model 12.94679 is a ceramic surface-mount oscillator operating at a frequency of 54 MHz. It utilizes HCMOS logic output and features a tri-state function with an output enable capability. The device operates on a 3.3V supply voltage and is housed in a compact 4-SMD, no-lead package.

Feature Summary

• Generates a stable 54 MHz clock signal using HCMOS technology
• Includes tri-state control for output enable management
• Designed for surface-mount assembly via a 4-pad configuration

Applications

• General-purpose digital clock generation
• Microprocessor system timing
• Communication interface synchronization

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 3.3V supply requirement aligns with the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when a fixed 54 MHz frequency is required for HCMOS-compatible circuits. Ensure the application supports the 3.3V operating voltage and requires a small form factor suitable for 4-SMD no-lead mounting constraints.

Part Context

This part belongs to the standard crystal oscillator family manufactured by Geyer Electronic America, Inc., which specializes in quartz-based timing solutions. The 12.94679 designation identifies a specific frequency variant within their industrial-grade ceramic oscillator lineup.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains the 54 MHz frequency, 3.3V supply, and 4-SMD pinout compatibility.
