9FGL6251AP201NDGI8

Overview

The 9FGL6251AP201NDGI8 is a clock generator and buffer from the Renesas 9FGL6251 series, designed for intelligent PCIe clocking in NVMe SSD applications. It supports Common (CC) and Independent Reference (IR) architectures with LP-HCSL differential outputs at 100MHz. The device features automatic input clock detection, integrated crystal options, and SMBus-selectable spread spectrum clocking (-0.25% to -0.5%). It operates on 2.5V or 3.3V supplies and includes integrated output terminations to reduce external component count.

Feature Summary

• Intelligent PCIe Clock Buffer/Generator for NVMe SSDs supporting CC and IR architectures
• Two 100MHz Low-power HCSL (LP-HCSL) outputs with 85Ω impedance and integrated terminations
• Automatic input clock detection and mode switching with open-drain status output
• SMBus-selectable Spread Spectrum Clocking (SSC) ranging from -0.25% to -0.5%

Applications

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

Procurement Notes

Verify the specific suffix 'P201' against official Renesas documentation to confirm exact configuration parameters, as datasheets often group variants under the root part number 9FGL6251. Confirm package type availability and moisture sensitivity levels prior to ordering, as these details are critical for surface-mount assembly processes.

Selection Notes

Select this component for designs requiring low-jitter PCIe clocking with integrated termination resistors to save board space. Ensure the design supports the required 2.5V or 3.3V supply voltage. Verify that the system architecture aligns with either Common Clock or Independent Reference modes supported by the device's internal logic.

Part Context

This part belongs to the 9FGL6251 family of intelligent clock buffers. It serves as a specialized solution for high-speed serial interface clock distribution, specifically optimized for the stringent jitter requirements of PCIe Gen1 through Gen4 standards used in modern solid-state drives.

Replacement Considerations

Consult the Renesas 9FGL6251 datasheet for direct pin-compatible alternatives within the same family, such as the 9FGL6251AQ or 9FGL6251AP variants with different packaging or SSC configurations.
