ICS954103EFLN

Overview

The ICS954103EFLN is an application-specific timing control hub designed for Intel P4 processor platforms. Manufactured by Renesas Electronics Corporation, this integrated circuit operates within a supply voltage range of 3.3V and supports surface-mount installation in a 56-BSSOP package with a width of 7.50mm. It functions as a single-circuit clock generator intended to manage timing signals for specific system architectures.

Feature Summary

• Designed specifically for Intel CPU and PCI Express (PCIe) applications
• Operates at a fixed supply voltage of 3.3V
• Available in a 56-SSOP surface-mount package

Applications

• Intel P4 processor systems
• PCI Express (PCIe) interface timing
• System clock distribution hubs

Procurement Notes

Verify the manufacturer designation, as the component is historically associated with IDT before its acquisition by Renesas. Confirm the exact package dimensions and pinout compatibility with the target PCB footprint. Ensure the 3.3V supply requirement aligns with the system design specifications.

Selection Notes

Select this component only if the design requires a dedicated timing hub for legacy Intel P4 architectures. The fixed 3.3V operation limits use in lower-voltage modern designs. Verify that the 56-SSOP package size fits the available board space constraints.

Part Context

This part belongs to the family of timing control hubs used in early 2000s PC architecture. It serves as a central clock generator for chipset synchronization. The device integrates multiple clock outputs into a single solution to reduce board complexity for P4-based motherboards.

Replacement Considerations

Cross-reference with other P4-compatible timing controllers from IDT or Renesas. Verify electrical pinouts and functional equivalence before substitution.
