ICS950405AFLF

Overview

The ICS950405AFLF is a system clock generator from the TCH series, designed for AMD-K8 platform timing control. It features an integrated PLL and accepts a crystal input to generate up to 20 differential-free clock outputs with a 1:20 ratio. The device operates within a 3.135V to 3.465V supply range and supports frequencies up to 300MHz. It is housed in a 48-SSOP surface-mount package and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Integrated PLL for system clock generation
• 1:20 output ratio supporting up to 20 clock signals
• Crystal input interface
• Optimized for AMD CPU and Timing Control Hub applications

Applications

• AMD-K8 platform timing control
• System clock distribution for AMD CPUs

Procurement Notes

Verify the specific suffix 'AFLF' against official Renesas documentation to confirm pinout compatibility and manufacturing lot details. Ensure the 48-SSOP package dimensions match the target PCB footprint. Confirm that the commercial temperature range (0°C to 70°C) meets the operational requirements of the final assembly environment.

Selection Notes

Select this component when designing for AMD-K8 architectures requiring a single-input, multi-output clock solution. The 300MHz maximum frequency and 1:20 ratio are key constraints. Ensure the design accommodates the 3.135V–3.465V supply voltage window and utilizes a crystal oscillator as the reference source.

Part Context

This part belongs to the TCH series, which specializes in timing control solutions. It is specifically engineered to meet the stringent clocking requirements of AMD processor platforms, providing stable and synchronized clock signals for system components.

Replacement Considerations

Check for direct cross-references in Renesas's current portfolio. Verify if newer generations of the TCH series offer compatible pinouts and electrical specifications for drop-in replacement.
