ICS9FG108DGLF

Overview

The ICS9FG108DGLF is a clock frequency timing generator manufactured by Renesas Electronics Corporation. It features a single PLL circuit with a 1:9 input-to-output ratio, designed for Intel CPU servers, PCI Express (PCIe), and SATA applications. The device accepts clock or crystal inputs and provides HCSL outputs with a maximum frequency of 400 MHz. It operates on a supply voltage ranging from 3.135 V to 3.465 V within an ambient temperature range of 0°C to 70°C. The component is housed in a 48-TFSOP package with a width of 6.10 mm.

Feature Summary

• Single PLL circuit supporting 1:9 input-to-output frequency ratio
• HCSL output signaling optimized for PCIe and SATA interfaces
• Operates at frequencies up to 400 MHz with 3.3V nominal supply
• Available in 48-TSSOP surface-mount package

Applications

• Intel CPU Server systems
• PCI Express (PCIe) clock generation
• SATA interface timing

Procurement Notes

Verify the specific suffix 'D' against official Renesas documentation to confirm any distinct electrical or mechanical variations compared to standard variants like the EGLF. Ensure the 48-TSSOP footprint matches the design layout. Confirm RoHS compliance status through the manufacturer's current product compliance reports before finalizing procurement.

Selection Notes

Select this component when a 1:9 clock distribution ratio is required for PCIe or SATA subsystems. The HCSL output type suits low-voltage logic interfaces common in server platforms. Verify that the 0°C to 70°C commercial temperature range meets the system environmental requirements. Ensure the 400 MHz maximum frequency covers the target bus speeds.

Part Context

This part belongs to the 9FG108 family of clock synthesizers and jitter cleaners from Renesas. These devices are engineered to provide precise clock signals for high-speed digital interfaces. The family typically supports multiple output configurations to simplify board design in complex computing architectures.

Replacement Considerations

The ICS9FG108EGLF shares the same 48-TSSOP package and core specifications but may differ in operating temperature or packaging style. Cross-reference the exact suffix requirements with Renesas datasheets to ensure functional compatibility.
