ICS9FG108DFILF

Overview

The ICS9FG108DFILF is a clock frequency timing generator manufactured by Renesas Electronics Corporation. It features a single PLL circuit with one input and nine outputs, providing a 1:9 ratio. The device supports HCSL output signaling and accepts crystal or clock inputs. It operates within a supply voltage range of 3.135V to 3.465V and achieves a maximum frequency of 400MHz. Designed for surface mount installation, it is housed in a 48-BSSOP package (0.295" width) and functions reliably across an extended temperature range of -40°C to +85°C.

Feature Summary

• Single PLL circuit with 1:9 input-to-output ratio
• HCSL output signaling compatible with PCIe and SATA standards
• Extended industrial operating temperature range (-40°C to +85°C)
• 48-SSOP surface-mount package

Applications

• Intel CPU Server systems
• PCI Express (PCIe) interface clocks
• SATA storage controller timing

Procurement Notes

Verify the specific suffix 'DF' against official Renesas documentation to confirm pinout compatibility and electrical characteristics relative to other variants in the 9FG108 series. Ensure the 48-BSSOP footprint matches the target PCB design. Confirm RoHS compliance status through the manufacturer's current product compliance reports before finalizing procurement specifications.

Selection Notes

Select this component when a 1:9 clock distribution ratio is required for Intel server architectures or high-speed serial interfaces like PCIe and SATA. The -40°C to +85°C rating makes it suitable for industrial environments. Compare against the 9FG108EGLF if a commercial temperature range (0°C to 70°C) suffices, as the DF variant offers broader thermal coverage.

Part Context

This part belongs to the 9FG108 family of clock synthesizers designed for data communications. It serves as a jitter cleaner and frequency multiplier for critical system buses. The device integrates a phase-locked loop to generate stable clock signals from a reference crystal or external clock source, ensuring signal integrity for downstream logic components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing with the 9FG108EGLF requires verification of temperature range differences and package pinout compatibility.
