954310BGLF

Application Specific Clock/Timing Overview

The Renesas 954310BGLF is a programmable Timing Control Hub designed for Intel P4 processors and chipsets, compliant with the CK410M specification. It operates on a single 3.3V supply and utilizes a 14.318MHz crystal input. The device generates multiple clock outputs including differential CPU pairs, PCI Express pairs, SATA, USB, and PCI clocks. Key electrical parameters include 0.7V current-mode differential signaling for high-speed interfaces and specific frequency outputs such as 33MHz for PCI and 48MHz for USB. It is housed in a 64-pin TSSOP package.

Application Specific Clock/Timing Feature Summary

• CK410M-compliant clock synthesizer for Intel P4 processors
• Generates 2 differential CPU pairs and 6 differential PCI Express pairs
• Includes selectable differential pairs for CPU_ITP/PCIEX and LCDCLK/PCIEX/27MHz
• Provides dedicated outputs for SATA (0.7V differential), USB (48MHz), and PCI (33MHz)

Application Specific Clock/Timing Applications

• Intel P4 processor-based desktop systems
• Intel chipset motherboard designs
• Timing control hubs requiring CK410M compliance

Application Specific Clock/Timing Procurement Notes

The 954310BGLF is listed as obsolete. Verification of availability should focus on surplus channels or last-time buy notices from authorized distributors. Confirm lead count and temperature grade specifications against original datasheets before procurement.

Application Specific Clock/Timing Selection Notes

Select this component only for legacy Intel P4 platform designs requiring CK410M compliance. Ensure the design supports the required 14.318MHz external crystal and load capacitors. Verify that the 64-pin TSSOP package footprint matches the PCB layout constraints.

Application Specific Clock/Timing Part Context

This part belongs to the IDT/Renesas Timing Control Hub family, originally developed by Integrated Device Technology (IDT) before its acquisition by Renesas Electronics. It serves as a specialized clock generator for early 2000s PC architectures, distinct from modern general-purpose clock synthesizers.

Application Specific Clock/Timing Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete model. Designers may need to evaluate newer Renesas timing controllers or generic clock generators, ensuring compatibility with CK410M specifications and pinout requirements.
