9FG108EGILF

Overview

The Renesas 9FG108EGILF is a clock synthesizer and jitter cleaner integrated circuit designed for high-speed digital applications. It features an internal Phase-Locked Loop (PLL) to generate frequencies up to 400 MHz from crystal or clock inputs. The device provides eight HCSL outputs with a 1:9 input-to-output ratio, supporting differential output configurations. Operating on a single 3.135 V to 3.465 V supply, it is housed in a 48-TFSOP package. The component supports spread spectrum clocking and is rated for industrial temperatures ranging from -40°C to +85°C.

Feature Summary

• Eight HCSL outputs with configurable differential pairs
• Internal PLL supporting frequencies up to 400 MHz
• Spread spectrum clocking capability for EMI reduction
• Industrial temperature range (-40°C to +85°C)

Applications

• Intel CPU server systems
• PCI Express (PCIe) interface clocks
• SATA storage controllers

Procurement Notes

Verify the specific suffix 'EGILF' against official Renesas documentation to confirm the extended industrial temperature range and TSSOP package variant. Datasheets may list aliases such as ICS9FG108EGILF; ensure the part number matches the required electrical specifications and pinout before procurement.

Selection Notes

Select this model when eight synchronized HCSL outputs are required for PCIe or SATA architectures. Ensure the design accommodates the 3.3 V nominal supply voltage and the 48-pin footprint. Verify that the 400 MHz maximum frequency meets the target bus speed requirements.

Part Context

This component belongs to the 9FG108 family of clock generators. Variants within the family differ by package type (TSSOP vs SSOP), temperature rating (commercial vs industrial), and output count. The EGILF designation specifically denotes the industrial grade version in the 48-lead thin-shrink small-outline package.

Replacement Considerations

Cross-reference with the 9FG108EGLFT for commercial temperature variants or the 9FG108EFLFT for SSOP packaging alternatives. Confirm pin compatibility and electrical parameters match the existing design constraints before substitution.
