12.94494

Overview

The Geyer Electronic America, Inc. model 12.94494 is a standard crystal oscillator (XO) operating at a frequency of 1 MHz. It utilizes CMOS and TTL output logic levels and functions within a supply voltage range of 5V. The device features tri-state output enable capability for power management control. Designed for surface-mount installation, it offers reliable frequency generation for digital circuit timing applications.

Feature Summary

• Supports both CMOS and TTL output logic standards
• Includes tri-state functionality for output enable control
• Designed for surface-mount technology integration

Applications

• Digital system clock generation
• Microcontroller timing sources
• General-purpose electronic circuit synchronization

Procurement Notes

Verify the specific package dimensions and pin configuration against your PCB footprint before ordering. Confirm that the 5V supply requirement aligns with your system's power rails. Ensure the tri-state control signal is properly routed to the enable pin in your schematic design to utilize the low-power standby mode effectively.

Selection Notes

Select this component when a 1 MHz reference frequency is required for systems compatible with CMOS or TTL interfaces. Consider the tri-state feature if power conservation during idle periods is necessary. Verify that the operating temperature range meets your environmental specifications and that the surface-mount form factor fits your assembly constraints.

Part Context

This oscillator belongs to the standard XO category from Geyer Electronic America, Inc., a manufacturer specializing in frequency control products. The company provides quartz crystals, oscillators, and ceramic resonators for global markets. This specific part represents a basic timing solution for general electronic applications requiring stable frequency generation.

Replacement Considerations

Check for direct substitutes with identical 1 MHz frequency, 5V supply, and CMOS/TTL output types. Ensure any replacement maintains the same surface-mount package dimensions and pinout compatibility. Verify that the substitute also supports tri-state operation if that feature is critical to your design.
