9FGU0841AKLFT

Overview

The Renesas Electronics Corporation 9FGU0841AKLFT is an 8-output clock generator designed for PCI Express (PCIe) Gen1, Gen2, and Gen3 applications. It operates with a 1.5V supply voltage and supports frequencies up to 200MHz. The device integrates a Phase-Locked Loop (PLL) for clock generation and distribution. It utilizes a 48-VFQFPN package with dimensions of 6x6mm and a 0.4mm pitch. The component is RoHS compliant and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Supports PCIe Gen1, Gen2, and Gen3 standards
• Provides 8 differential outputs with low power consumption
• Integrated PLL for clock generation
• Operates on a single 1.5V supply

Applications

• PCI Express Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Procurement Notes

Verify the specific suffix 'AKLFT' against the manufacturer's current datasheet to confirm pinout and electrical specifications. Check for Product Change Notifications (PCNs) regarding assembly sites or material changes. Confirm availability status as this series may have discontinued variants. Ensure the 48-VFQFPN package matches the target PCB footprint.

Selection Notes

Select this component when designing for PCIe Gen1-Gen3 interfaces requiring low-voltage operation. Compare output drive strength and jitter performance against other members of the 9FGU/9FGV families. Verify that the 1.5V supply rail is compatible with the system power architecture. Consider thermal dissipation requirements for the VFQFPN package in dense layouts.

Part Context

This part belongs to the Renesas IDT 9FGU series of ultra-low-power PCIe clock generators. It is functionally related to the 9FGU0831 and 9FGV0841 models, which offer similar 8-output configurations but may differ in voltage levels or supported PCIe generations. The 9FGU series specifically targets 1.5V applications.

Replacement Considerations

The 9DBL0841BKILFT is listed as a discontinued alternative by distributors, though it is a buffer rather than a generator. For direct replacements, consult the Renesas product selector for active 8-output 1.5V PCIe clock generators such as updated 9FGU or 9FGV variants.
