ICS9FG108DFILFT

Overview

The ICS9FG108DFILFT is a clock frequency timing generator manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.135V to 3.465V and supports a maximum frequency of 400MHz. The device features one circuit with a 1:9 input-to-output ratio, utilizing HCSL output levels. It accepts clock or crystal inputs and is housed in a 48-BSSOP package (48-SSOP). Designed for surface mount installation, it functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Integrated PLL for precise clock generation
• HCSL output interface compatible with high-speed digital systems
• Supports 1:9 frequency multiplication ratio
• Extended industrial temperature range (-40°C to 85°C)

Applications

• Intel CPU Server platforms
• PCI Express (PCIe) interfaces
• SATA clock distribution

Procurement Notes

Verify the specific suffix 'D' against official Renesas documentation to confirm any distinct marking, tape-and-reel specifications, or environmental compliance differences compared to standard variants. Ensure the 48-SSOP footprint matches the target PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 400MHz maximum frequency and 1:9 ratio are required for PCIe or SATA applications. Confirm that the HCSL output swing meets the receiver input requirements of the downstream components. Verify that the 48-SSOP package dimensions fit within the available board space and thermal management plan.

Part Context

This part belongs to the 9FG108 series of clock synthesizers designed for high-performance computing environments. It serves as a jitter cleaner and frequency multiplier for critical system clocks in server architectures.

Replacement Considerations

Check Renesas datasheets for direct pin-compatible alternatives within the 9FG108 family. Verify electrical parameters such as output drive strength and phase noise specifications if substituting with other manufacturers.
