ICS953401CFT

Overview

The ICS953401CFT is a timing control hub designed for PCI Express (PCIe) applications. Manufactured by Renesas Electronics Corporation, this integrated circuit operates on a single 3.3V supply voltage and generates clock signals. It is housed in a 56-BSSOP surface-mount package with a width of 7.50mm. The device functions within an operating temperature range of 0°C to 70°C. It does not include an internal PLL and serves as a dedicated clock output controller for PCIe system architectures.

Feature Summary

• Designed specifically for PCI Express (PCIe) main-purpose applications
• Operates at a standard 3.3V supply voltage
• Available in a 56-SSOP surface-mount package

Applications

• PCI Express system clock distribution
• Timing control hubs for PCIe-based hardware

Procurement Notes

Verify the specific manufacturing lot date code and RoHS compliance status directly with authorized distributors or Renesas Electronics. Confirm that the 56-SSOP package dimensions match the design requirements. Ensure the 0°C to 70°C commercial temperature range is sufficient for the intended environment. Check for any end-of-life notices or last-time-buy notifications associated with this specific SKU.

Selection Notes

Select this component when a dedicated timing hub for PCIe interfaces is required. Ensure the design supports a 3.3V logic level. The 56-pin SSOP package requires appropriate PCB footprint planning. Consider thermal management if the ambient temperature approaches the upper limit of 70°C. Verify compatibility with the target PCIe generation specifications.

Part Context

This part belongs to the Application Specific Clock/Timing category from Renesas Electronics. It is distinct from general-purpose oscillators or programmable clock generators due to its fixed function for PCIe systems. The 56-SSOP form factor distinguishes it from larger BGA or smaller QFN alternatives in similar timing families.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided source material. Consult Renesas Electronics for current portfolio equivalents or cross-reference with other vendors offering PCIe timing controllers in 56-SSOP packages.
