090-44550-01

Overview

The Microsemi Corporation 090-44550-01 is an atomic clock oscillator operating at a nominal frequency of 10.0000 MHz with CMOS output logic. Designed for through-hole mounting in an 8-DIP module package, this component supports a wide supply voltage range of 4.5V to 32V. It functions within an industrial temperature range of -40°C to 75°C. As part of the Application Specific Clock/Timing category, it provides stable timing signals without internal PLL circuitry, suitable for applications requiring robust atomic timekeeping in varied electrical environments.

Feature Summary

• Atomic clock technology providing high stability at 10.0000 MHz
• Wide operating voltage range from 4.5V to 32V
• CMOS output format for digital interface compatibility
• Through-hole 8-DIP module packaging

Applications

• Telecommunications base station synchronization
• Navigation and GPS reference systems
• Test and measurement equipment requiring precise timing

Procurement Notes

Verify the specific frequency stability and aging rate specifications against the official datasheet, as these critical performance metrics are not detailed in the provided product fields. Confirm that the 8-DIP module form factor matches the target PCB footprint requirements. Ensure the 4.5V to 32V supply range aligns with the system power design constraints.

Selection Notes

Select this component when a wide input voltage capability is required compared to standard 5V or 3.3V oscillators. The atomic nature of the oscillator makes it suitable for applications needing long-term frequency stability without external oven control. Compare the physical dimensions of the 8-DIP module against available board space to ensure proper clearance for mounting.

Part Context

This model belongs to Microsemi's family of atomic clock oscillators, which utilize rubidium or cesium standards for superior frequency accuracy. Unlike standard crystal oscillators, these devices maintain tight tolerance over extended periods and temperature variations. The 090 series typically denotes specific module configurations within their timing portfolio.

Replacement Considerations

Direct replacements must match the 10 MHz frequency, CMOS output, and 8-DIP through-hole package. Verify that substitute atomic oscillators support the same 4.5V to 32V input range. Check if alternative models offer compatible pinouts or require adapter solutions for existing PCB layouts.
