9FGL6251AQ202LTGI8

Overview

The 9FGL6251AQ202LTGI8 is a PCIe clock generator from the Renesas 9FGL6251 series, designed for NVMe SSD applications. It features two differential LP-HCSL outputs with integrated 85-ohm terminations. The device supports SRIS (Separate Reference Independent Spread) architecture by default, utilizing -0.5% spread spectrum clocking. It accepts 25MHz or 33.33MHz reference clocks and operates on a single 3.3V supply. The component is housed in a 4mm x 4mm 28-LGA package.

Feature Summary

• Supports SRIS clocking architecture with default -0.5% spread spectrum
• Two differential LP-HCSL outputs with integrated 85-ohm termination resistors
• Accepts 25MHz or 33.33MHz crystal or LVCMOS reference inputs
• Single 3.3V power supply operation

Applications

• NVMe SSD designs
• PCIe master/slave clocking
• Clock multiplexing systems

Procurement Notes

Verify the specific suffix LTGI8 corresponds to the reel packaging configuration of 2500 units per reel. Confirm moisture sensitivity level requirements during storage and handling. Ensure the design utilizes the SRIS architecture compatible with the -0.5% SSC default setting.

Selection Notes

Select this part over the AQ302 variant when SRIS architecture with -0.5% SSC is required rather than CC or SRNS modes. The AQ202 designation indicates the specific pinout and feature set for SRIS/CC architectures. Verify compatibility with 85-ohm system impedance due to integrated terminations.

Part Context

This component belongs to the 9FGL6251 family of intelligent PCIe clock buffers and generators. The 'AQ' prefix denotes specific package and feature variations within the series. The '202' suffix typically identifies the SRIS/CC configuration variant, distinguishing it from other architectural options like SRNS.

Replacement Considerations

The 9FGL6251AQ201LTGI8 is a related variant within the same family. Verify if the target application requires the specific SRIS default settings of the AQ202 or if the alternative configuration is acceptable.
