ICS954148AFLF

Overview

The ICS954148AFLF is a dedicated timing controller integrated circuit designed for Intel CPU and PCI Express (PCIe) applications. Manufactured by Renesas Electronics Corporation, this device operates on a single 3.3V supply voltage and supports surface mount installation in a 56-BSSOP package. It functions as a clock generator with one circuit, providing clock outputs suitable for system timing requirements within an operating temperature range of 0°C to 70°C.

Feature Summary

• Designed specifically for Intel CPU and PCI Express (PCIe) platform timing control
• Operates at a standard 3.3V supply voltage
• Housed in a 56-lead BSSOP package with a width of 7.50mm
• Supports industrial commercial temperature range from 0°C to 70°C

Applications

• Intel-based motherboard systems requiring precise clock distribution
• PCI Express interface timing synchronization
• Server and workstation mainboard designs

Procurement Notes

Verify the specific revision level and RoHS compliance status through official Renesas documentation prior to procurement, as manufacturing parameters may vary across production batches. Confirm package dimensions against the 56-BSSOP specification sheet to ensure compatibility with existing PCB footprints and assembly processes.

Selection Notes

Select this component when a fixed-frequency or non-programmable clock solution is required for legacy Intel CPU and PCIe architectures. Ensure the design environment remains within the specified 0°C to 70°C operational limit. Verify that the 3.3V logic levels match the target system's voltage domain requirements.

Part Context

This part belongs to the family of application-specific clock controllers optimized for high-speed digital interfaces. It serves as a critical timing element in systems utilizing Intel processors and PCIe buses, replacing discrete oscillator solutions to reduce board space and improve signal integrity.

Replacement Considerations

Cross-reference with other 56-SSOP clock generators from Renesas if pin-to-pin compatibility is required. Verify electrical specifications such as output drive strength and jitter performance against the original design requirements before substitution.
