9FG104EFILFT

Overview

The Renesas 9FG104EFILFT is a clock synthesizer and jitter cleaner designed for Intel CPU servers, PCI Express (PCIe), and SATA applications. It operates as an extended spectrum clock generator with a maximum output frequency of 400 MHz. The device features a single output circuit configured in a 1:5 input-to-output ratio, utilizing HCSL signaling levels. It accepts crystal or clock inputs up to 27.5 MHz and functions within a supply voltage range of 3.135 V to 3.465 V. The component is housed in a 28-SSOP package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports PCIe Gen 2 synthesizer requirements with integrated jitter cleaning capabilities
• Provides one output channel with a 1:5 input-to-output frequency ratio
• Operates on a 3.135 V to 3.465 V power supply with typical current consumption of 106 mA
• Housed in a 28-SSOP surface-mount package suitable for space-constrained designs

Applications

• Intel CPU server platforms requiring precise clock distribution
• PCI Express (PCIe) interface clock generation and synchronization
• SATA controller clock synthesis for storage subsystems

Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to commercial variants. Confirm the package type is 28-SSOP rather than TSSOP. Check RoHS compliance status and moisture sensitivity level (MSL 1) before assembly planning. Ensure the ordering quantity matches the manufacturer's standard packaging unit of 1,500 units per reel.

Selection Notes

Select this part when a single differential HCSL output is required for PCIe or SATA links. Compare against the 9FG104EGLF if a TSSOP package or commercial temperature range (0°C to +70°C) is preferred instead. Verify that the 400 MHz maximum frequency meets the target system clock requirements. Ensure the design accommodates the 3.3V nominal supply voltage constraints.

Part Context

This component belongs to the 9FG104 family of clock synthesizers manufactured by Renesas Electronics. It serves as a specialized timing solution for high-speed serial interfaces. The 'EFILFT' designation specifies the SSOP package, extended temperature rating, and lead-free tape-and-reel packaging format.

Replacement Considerations

The ICS9FG104EFILFT is an alias for this part number. For package variations, consider the 9FG104EGLFT which uses a 28-TSSOP housing. If a wider temperature range is not needed, the commercial grade 9FG104CGLFT may be available but is listed as obsolete.
