ICS954226AG

Overview

The ICS954226AG is a single-circuit application-specific clock controller manufactured by Renesas Electronics Corporation. Designed for Intel CPU-M, Intel CPU, and PCI Express (PCIe) platforms, this device generates a maximum frequency of 400MHz with one clock output. It operates on a 3.3V supply voltage within an ambient temperature range of 0°C to 70°C. The component utilizes a surface-mount 56-TFSOP package, specifically identified as 56-TSSOP in supplier documentation, measuring 6.10mm in width. This integrated circuit functions without an internal Phase-Locked Loop (PLL).

Feature Summary

• Single-circuit clock controller optimized for Intel CPU-M and PCIe applications.
• Generates clock signals up to 400MHz with a 3.3V power supply.
• Available in a 56-TFSOP (56-TSSOP) surface-mount package.

Applications

• Intel CPU-M systems
• Intel CPU platforms
• PCI Express (PCIe) interfaces

Procurement Notes

Verify the specific suffix requirements for the final orderable part number, as the base model may require additional characters for packaging or compliance variations. Confirm RoHS status and end-of-life notifications through official Renesas channels prior to procurement planning.

Selection Notes

Select this component when designing for legacy Intel CPU-M or PCIe architectures requiring a fixed 400MHz clock source. Ensure the design accommodates the 56-TSSOP footprint and 3.3V logic levels. Verify thermal constraints against the 0°C to 70°C operating range for the target enclosure environment.

Part Context

This timing controller belongs to Renesas's portfolio of specialized clock solutions for computing infrastructure. It serves as a dedicated timing generator for processor and expansion bus interfaces, replacing discrete oscillator circuits with a single integrated solution for signal integrity and board space optimization.

Replacement Considerations

Check for direct pin-compatible substitutes within the same Renesas family. Verify that alternative devices support the required 400MHz frequency and 56-pin TSSOP package dimensions for mechanical fit.
