12.73002

Overview

The Geyer Electronic America, Inc. model 12.73002 is a standard HCMOS clock oscillator designed for surface-mount applications. It operates at a nominal frequency of 40 MHz and utilizes a 4-SMD, no-lead package configuration. The device functions with a 3.3V supply voltage and includes an enable/disable control feature for power management. It maintains a frequency stability specification within the temperature range of -40°C to +85°C, ensuring reliable performance in industrial environments.

Feature Summary

• HCMOS output signal compatibility
• Integrated enable/disable functionality
• Industrial temperature range operation

Applications

• Telecommunication equipment
• Industrial control systems
• Computer peripheral interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct packaging and tolerance specifications. Confirm that the 4-SMD footprint matches the target PCB design. Cross-reference the enable pin logic level requirements with the system microcontroller outputs to guarantee proper interface compatibility during integration.

Selection Notes

Select this component when a stable 40 MHz reference is required for HCMOS-compatible digital circuits. The choice is driven by the need for low-power operation via the enable feature and robust performance across wide industrial temperature variations. Ensure the 3.3V supply rail aligns with the system architecture before finalizing the bill of materials.

Part Context

This oscillator belongs to Geyer Electronic America's SMD clock oscillator family, which specializes in quartz-based frequency generation. The brand is recognized for manufacturing precision timing components for telecommunications and industrial sectors. This specific model represents a standard solution for general-purpose clocking needs within their ceramic and quartz product portfolio.

Replacement Considerations

Consult official substitution lists for equivalent 40 MHz HCMOS oscillators with identical 4-SMD footprints. Verify that any alternative part supports the same 3.3V operating voltage and enable/disable control scheme. Ensure thermal stability ratings match or exceed the -40°C to +85°C requirement for the intended application environment.
