9FGL6241AP301NDGI8

Overview

The 9FGL6241AP301NDGI8 is a PCI Express (PCIe) clock generator IC manufactured by Renesas Electronics. It operates with a maximum frequency of 100MHz and features one output circuit. The device supports HCSL input signaling and provides LP-HCSL and LVCMOS output types. It utilizes a PLL architecture and offers a differential input-to-output ratio of 3:2. The component is housed in a 28-VFQFPN package with dimensions of 4mm x 4mm and includes an exposed pad for thermal management.

Feature Summary

• Supports PCIe Common (CC) and Independent Reference (IR) clocking architectures
• Integrates automatic detection of input clock presence and mode switching
• Features integrated terminations on differential outputs to reduce external resistor count
• Provides SMBus-selectable spread spectrum capabilities

Applications

• Single and dual-ported NVMe SSDs
• U.2 and M.2 form factor storage devices
• PCIe master/slave clock multiplexing applications

Procurement Notes

Verify the specific suffix NDGI8 against official Renesas documentation to confirm reel packaging and lead-free status. Confirm availability through authorized distributors as standard stock levels may vary. Ensure compliance with RoHS directives for the intended application environment.

Selection Notes

Select this model for designs requiring 100MHz PCIe clock generation with low-power HCSL outputs. Compare with the 9FGL6251 series if higher output counts or different termination impedances are required. Verify that the 28-VFQFPN package fits the PCB footprint constraints.

Part Context

This component belongs to the 9FGL6241 family of intelligent PCIe clock buffers and generators. It is designed to replace discrete clock solutions, offering reduced board space and improved signal integrity through integrated features such as automatic clock detection and spread spectrum modulation.

Replacement Considerations

Check for direct pin-compatible replacements within the 9FGL6241 series. Evaluate the 9FGL6251 series for similar functionality with potentially different output configurations. Verify that any substitute maintains the same voltage supply requirements and temperature range.
