ICS9LPRS397EKLFT

Overview

The ICS9LPRS397EKLFT is a PC main clock generator manufactured by Renesas Electronics Corporation. Designed for Intel CPU server applications, this integrated circuit operates on a single 3.3V supply voltage and supports crystal inputs to generate precise clock outputs. The device functions without an internal Phase-Locked Loop (PLL) and is housed in a 72-VFQFPN package with dimensions of 10x10 mm and an exposed pad. It is rated for industrial operation within a temperature range of 0°C to 70°C.

Feature Summary

• Designed specifically for Intel CPU server platforms
• Operates at a fixed 3.3V supply voltage
• Crystal input configuration for clock generation
• Housed in a compact 72-VFQFPN (10x10mm) surface-mount package

Applications

• Intel CPU Server systems
• PC Main Clock distribution
• Server timing control hubs

Procurement Notes

Verify the component status as active or obsolete through official Renesas channels before procurement. Confirm that the 72-VFQFPN package dimensions match the design requirements. Ensure the 3.3V supply specification aligns with the target system power rails. Check for any specific RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component when a dedicated main clock solution for Intel CPU servers is required. The absence of an internal PLL indicates it may be used where external frequency synthesis is managed elsewhere or for fixed-frequency needs. Ensure the 0°C to 70°C operating temperature range meets the environmental constraints of the deployment location.

Part Context

This part belongs to the Application Specific Clock/Timing category from Renesas Electronics Corporation. It serves as a specialized clock generator distinct from general-purpose oscillators, targeting high-reliability server infrastructure environments requiring stable timing signals for processor subsystems.

Replacement Considerations

Consult Renesas datasheets for direct pin-to-pin replacements within the same 72-VFQFPN form factor. Verify compatibility with Intel CPU generations supported by alternative models in the 9LPRS series.
