952911BFLF

Application Specific Clock/Timing Overview

The Renesas 952911BFLF is a clock controller hub designed for Intel Pentium 4 platforms. It operates on a single 3.3V supply voltage and functions within an industrial temperature range of 0°C to 70°C. The device is housed in a 48-lead Shrink Small Outline Package (SSOP) with a width of 7.50mm. As a specialized timing component, it generates necessary clock signals for system synchronization. The part is identified by the base number ICS952911B and is currently classified as obsolete.

Application Specific Clock/Timing Procurement Notes

The 952911BFLF is officially listed as obsolete by Renesas Electronics Corporation. Procurement is restricted to remaining stock or secondary market channels. Verify the specific manufacturing date code and physical condition when sourcing from non-direct suppliers, as availability is limited and subject to change without notice.

Application Specific Clock/Timing Selection Notes

Engineers replacing this component must verify pin compatibility and electrical specifications against the target Pentium 4 chipset requirements. Since the original part is obsolete, substitute selection should focus on functionally equivalent clock controllers supporting the same voltage and package constraints. Ensure any replacement maintains signal integrity for the specific bus frequencies required by the legacy platform.

Application Specific Clock/Timing Part Context

This component belongs to the ICS952911 family of clock controllers. The 'LF' suffix indicates lead-free compliance. The device was manufactured under the Integrated Device Technology (IDT) brand prior to its acquisition by Renesas Electronics. It serves as a critical timing element for older PC architectures relying on the Pentium 4 processor core.

Application Specific Clock/Timing Replacement Considerations

No direct public substitute part numbers are confirmed for immediate drop-in replacement. Legacy equivalents may include other IDT/Renesas Pentium 4 clock generators such as the 952911 series variants, but functional verification is required.
