9FGL6241AP201NDGI

Overview

The 9FGL6241AP201NDGI is a PCI Express (PCIe) clock generator IC manufactured by Renesas Electronics. It operates with a single output frequency of 100MHz and utilizes a 28-VFQFPN (4x4mm) package. The device supports LP-HCSL differential output signaling with an integrated 100Ω output impedance, eliminating the need for external termination resistors. It accepts HCSL or LVCMOS input signals and functions as a zero-delay buffer or generator within PCIe architectures.

Feature Summary

• Integrated 100Ω output termination resistors for direct connection to transmission lines
• Supports Common Clock (CC), Separate Reference no Spread (SRnS), and Separate Reference Independent Spread (SRIS) architectures
• Single LP-HCSL differential output at 100MHz
• 28-VFQFPN (4x4mm) surface-mount package

Applications

• PCI Express clock distribution in server and storage systems
• Clock generation for PCIe Gen1 through Gen5 compliant devices
• Zero-delay buffering for high-speed serial interfaces

Procurement Notes

Verify the specific suffix 'NDGI' against the official Renesas datasheet to confirm lead-free status and tape-and-reel packaging configuration. Confirm RoHS compliance details directly from the manufacturer's documentation prior to procurement.

Selection Notes

Select this component when a single 100MHz PCIe clock output with integrated 100Ω termination is required. Ensure the design supports LP-HCSL signaling levels. Compare with the 9FGL6251 series if two differential outputs or internal crystal options are needed instead of a single output.

Part Context

This part belongs to the 9FGL6241/6251 family of intelligent PCIe clock buffers and generators. These devices are designed to meet the stringent jitter requirements of PCIe standards across multiple generations, providing flexible clocking solutions for master and slave devices.

Replacement Considerations

The 9FGL6251AP201NDGI serves as a functional alternative offering dual outputs instead of one. Verify pin compatibility and output impedance differences (85Ω vs 100Ω) before substitution.
