9FG108EFILFT

Overview

The Renesas 9FG108EFILFT is a clock synthesizer and jitter cleaner housed in a 48-BSSOP package. It operates on a single 3.135V to 3.465V supply with an operating temperature range of -40°C to 85°C. The device features one circuit with a 1:9 input-to-output ratio, supporting HCSL outputs. It integrates a PLL for frequency synthesis and accepts clock or crystal inputs. The maximum output frequency reaches 400MHz. Designed for Intel CPU servers, PCIe, and SATA applications, it supports spread spectrum clocking to reduce EMI.

Feature Summary

• Integrated PLL-based clock synthesizer and jitter cleaner
• HCSL output signaling with 1:9 input-to-output ratio
• Supports spread spectrum clocking for EMI reduction
• Operates within -40°C to 85°C industrial temperature range

Applications

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

Procurement Notes

Verify the specific suffix 'I' indicates the BSSOP-48 package variant distinct from other 9FG108 models. Confirm moisture sensitivity level (MSL 3) requirements for surface mount assembly processes. Ensure compatibility with 3.3V logic families when interfacing with downstream components.

Selection Notes

Select this component for designs requiring fixed-frequency HCSL generation from a single reference. Compare against programmable alternatives if dynamic frequency adjustment is needed. Verify that the 48-pin BSSOP footprint fits the PCB layout constraints compared to TSSOP or VQFPN options available in the same family.

Part Context

This part belongs to the 9FG108 series of clock generators manufactured by Renesas Electronics. It serves as a fixed-function solution for high-speed digital interfaces, differing from programmable PhiClock devices like the 9FGV series which offer software-configurable frequencies via I2C.

Replacement Considerations

The 9FG108EGLFT is a related model but utilizes a 48-TFSOP package and typically operates at 0°C to 70°C. Verify pinout compatibility and thermal performance before substituting into existing designs.
