9FGU0231AKLF

Overview

The 9FGU0231AKLF is a PCIe clock generator IC from Renesas Electronics, designed for PCI Express Gen1/2/3 applications. It features a single PLL circuit with a 1:3 input-to-output ratio. The device accepts LVDS or crystal inputs and provides LP-HCSL and LVCMOS outputs. It operates within a supply voltage range of 1.425V to 1.575V and supports maximum frequencies up to 100MHz. The component is housed in a 24-VFQFN package with exposed pads, suitable for surface mount installation.

Feature Summary

• Supports PCI Express Gen1, Gen2, and Gen3 standards
• Integrates low-power HCSL outputs to reduce external resistor count
• Utilizes a single PLL architecture for efficient clock synthesis

Applications

• PCI Express (PCIe) clock generation for Gen1/2/3 interfaces
• Server and storage system motherboard designs
• Peripheral component interconnect expansion cards

Procurement Notes

Verify the specific suffix 'AKLF' against the official Renesas datasheet to confirm pinout compatibility and electrical specifications. Ensure that the required output types (LP-HCSL and LVCMOS) align with the target design requirements. Confirm RoHS compliance status and moisture sensitivity level prior to procurement to ensure proper handling and storage conditions are met during assembly.

Selection Notes

Select this component when designing systems requiring dedicated clock sources for PCI Express interfaces. It is appropriate for applications needing both differential and single-ended outputs from a single source. Consider the thermal performance and power consumption characteristics relative to other clock generators in the portfolio to ensure optimal system efficiency and reliability.
