Procurement Notes

This component is marked as obsolete or discontinued by the manufacturer. Verification of availability should focus on surplus distributors or secondary market sources rather than direct manufacturer stock. Ensure compatibility with existing PCB footprints when sourcing replacements from alternative suppliers.

Selection Notes

Select this part only for designs specifically requiring Pentium 4 compatible clock control. Verify that the 48-SSOP package dimensions match the target board layout. Confirm that the 3.3V supply voltage aligns with the system power architecture before integration.

Part Context

The ICS952911BF belongs to the family of application-specific clock controllers developed for Intel Pentium 4 processors. It replaces discrete clock generator solutions by integrating multiple clock outputs into a single IC, reducing board space and complexity in desktop computer motherboards during the early 2000s era.

Replacement Considerations

As the part is discontinued, no official direct replacement is listed. Engineers must evaluate third-party clock generators with similar pinouts and electrical characteristics, ensuring support for Pentium 4 specific timing requirements.
