12.94751

Overview

The Geyer Electronic America, Inc. model 12.94751 is a standard HCMOS crystal oscillator operating at 50 MHz. It features a 3.3V supply voltage and includes tri-state output enable functionality. The component utilizes a 4-SMD, no lead package with dimensions of 3.2mm x 2.5mm. This device is designed for surface mount installation and provides reliable frequency control within its specified operational parameters.

Feature Summary

• Generates a stable 50 MHz signal using HCMOS logic levels
• Incorporates tri-state output capability for bus isolation
• Operates on a single 3.3V power supply rail

Applications

• Digital clock generation in microprocessor systems
• Synchronization interfaces for communication protocols
• Timing references for data acquisition circuits

Procurement Notes

Verify the specific ordering suffix to confirm the required packaging format, such as tape and reel or cut tape, as these affect handling procedures. Ensure the requested variant matches the exact electrical specifications and pin configuration documented in the official manufacturer datasheet before finalizing the purchase order.

Selection Notes

Select this component when a precise 50 MHz timing source is required for digital logic interfacing. The HCMOS output level ensures compatibility with standard CMOS inputs. Consider the physical footprint constraints of the 4-SMD package during PCB layout design to ensure adequate soldering clearance.

Part Context

This oscillator belongs to the family of frequency control products manufactured by Geyer Electronic America, Inc., which specializes in quartz crystals and resonators. The 12.94751 serves as an active timing element, contrasting with passive resonators by providing a ready-to-use square wave output without requiring external load capacitors.

Replacement Considerations

Cross-reference part numbers from other manufacturers offering 50 MHz HCMOS oscillators in 4-SMD packages. Verify that substitute components match the 3.3V supply requirement and tri-state output functionality to maintain circuit compatibility.
