ASM3P2180AF-08ST

Overview

The ASM3P2180AF-08ST is a frequency modulator and spread spectrum clock generator IC from onsemi. It operates at a frequency of 30MHz with one channel. The device supports an operating supply voltage range of 2.8V to 3.7V. It is housed in an 8-SOIC package, specifically defined as SOIC N-8 with dimensions of 0.154 inches (3.90mm) width.

Feature Summary

• Integrates spread spectrum clock generation functionality for electromagnetic interference reduction
• Provides pin-compatible replacement capabilities for existing clock generators in electronic designs
• Utilizes a compact PDSO package form factor

Applications

• General electronic devices requiring clock signal modulation
• Systems needing electromagnetic interference mitigation through spread spectrum techniques
• Designs utilizing standard 8-pin SOIC footprints for clock generation

Procurement Notes

Verify the specific suffix 'ST' against official onsemi documentation to confirm exact tape and reel packaging or temperature grade specifications. Ensure the 8-SOIC footprint matches the target PCB layout constraints. Confirm that the 30MHz output frequency aligns with system timing requirements before procurement.

Selection Notes

Select this component when a single-channel spread spectrum clock generator is required for EMI reduction. The 2.8V to 3.7V supply range suits low-voltage digital systems. Consider the 8-SOIC package size for space-constrained applications where pin compatibility with legacy clock generators is necessary.

Part Context

This part belongs to onsemi's family of frequency modulators and spread spectrum clock generators. These components are designed to reduce peak electromagnetic emissions by slightly modulating the clock frequency. The ASM3 series typically offers solutions for various clock frequencies and package options to support diverse electronic design needs.

Replacement Considerations

The datasheet indicates that the compact PDSO package offers a pin-compatible replacement for existing clock generators. Verify pinout compatibility with the original design if substituting other models in the ASM3 series.
