954310BGLFT

Application Specific Clock/Timing Overview

The IDT954310BGLFT is a programmable timing control hub designed for Intel P4 processors and chipsets, compliant with the Intel CK410M specification. It functions as a clock synthesizer driven by a 14.318MHz crystal. The device integrates multiple differential current-mode outputs, including two CPU pairs, six PCIe pairs, one SATA pair, and selectable pairs for CPU_ITP/PCIe and LCDCLK/PCIe/27MHz. Additional outputs include four PCI (33MHz) signals, two free-running PCICLK_F (33MHz), one USB (48MHz), one DOT (96MHz), and two reference clocks (14.318MHz).

Application Specific Clock/Timing Feature Summary

• Intel CK410M-compliant clock synthesis for P4 processors.
• Multiple differential current-mode output pairs (0.7V swing).
• Integrated support for PCIe, SATA, USB, and PCI interfaces.
• Single-chip solution driven by a 14.318MHz crystal.

Application Specific Clock/Timing Applications

• Intel P4 processor platforms.
• Intel chipset designs.
• Systems requiring integrated PCIe and SATA clock distribution.

Application Specific Clock/Timing Procurement Notes

The 954310BGLFT is listed as obsolete. Verification of availability should focus on surplus or secondary market sources rather than standard manufacturer distribution channels. Users must confirm the authenticity of components from non-primary distributors due to the end-of-life status.

Application Specific Clock/Timing Part Context

The 954310BGLFT belongs to the IDT954310 series of programmable timing control hubs. It was manufactured by Integrated Device Technology (IDT), which was acquired by Renesas Electronics Corporation. The component serves as a specialized clock generator for legacy high-performance computing architectures.

Application Specific Clock/Timing Replacement Considerations

As an obsolete component, direct replacements are not officially documented in the provided source material. Designers should evaluate newer Renesas timing solutions compatible with modern Intel architectures or verify pin-compatible alternatives through independent engineering analysis.
