ICS954148AFLFT

Overview

The ICS954148AFLFT is a timing control hub designed for Intel CPU and PCI Express (PCIe) applications. It operates on a single 3.3V supply voltage and functions as a clock generator within a single circuit configuration. The device is housed in a 56-BSSOP surface-mount package with a width of 7.50mm. It supports an industrial operating temperature range from 0°C to +70°C. This component serves as a dedicated clock solution for system synchronization without integrated PLL functionality.

Feature Summary

• Designed specifically for Intel CPU and PCIe interface synchronization
• Operates on a standard 3.3V power supply
• Housed in a compact 56-lead SSOP surface-mount package

Applications

• Intel-based motherboard clock distribution
• PCI Express peripheral timing generation
• System timing control hubs

Procurement Notes

Verify the specific manufacturing lot date code against current production status, as timing controllers may undergo lifecycle changes. Confirm that the 56-SSOP footprint matches the target PCB design constraints. Ensure the 0°C to 70°C commercial temperature rating meets the environmental requirements of the final assembly. Cross-reference the supplier device package designation to avoid pinout mismatches during integration.

Selection Notes

Select this component when a fixed or simple clock generation solution is required for Intel architectures without complex programmable PLL features. The 56-SSOP package is suitable for designs prioritizing board space efficiency over high-pin-count flexibility. Verify that the 3.3V logic levels align with the downstream receiver inputs. Consider thermal dissipation capabilities within the enclosed SSOP housing for continuous operation.

Part Context

This part belongs to the Renesas application-specific clock and timing category. It complements broader system timing solutions by providing dedicated clock outputs for high-speed interfaces like PCIe. Unlike general-purpose oscillators, it is optimized for specific processor bus requirements.

Replacement Considerations

Check for direct pin-to-pin replacements within the same Renesas timing family. Verify compatibility with existing Intel chipset specifications if substituting in established designs.
