9FGV0841AKLF

Overview

The Renesas Electronics 9FGV0841AKLF is a clock generator designed for PCI Express applications. It features a single circuit with a 1:9 input-to-output ratio, supporting up to 100 MHz maximum frequency. The device accepts crystal inputs and provides HCSL or LVCMOS outputs. It operates on a supply voltage ranging from 1.7 V to 1.9 V within an ambient temperature range of 0°C to 70°C. The component is housed in a 48-VFQFPN package with dimensions of 6x6 mm and includes an exposed pad for surface mount installation.

Feature Summary

• PCIe Clock Generator with 1:9 output ratio
• Supports HCSL and LVCMOS output formats
• Operates at 1.7 V to 1.9 V supply voltage
• Integrated PLL for clock generation

Applications

• PCI Express (PCIe) system clock distribution
• High-speed digital interface timing
• Server and storage motherboard designs

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and tape/reel specifications. Confirm moisture sensitivity level requirements for assembly processes. Ensure compatibility with the target PCB footprint for the 48-VFQFPN package. Check for any recent product change notifications regarding manufacturing sites or materials.

Selection Notes

Select this component when a PCIe application requires nine differential or single-ended clock outputs from a single crystal source. Verify that the required output logic levels match the available HCSL or LVCMOS options. Ensure the operating environment stays within the specified 0°C to 70°C temperature range. Confirm power supply constraints align with the 1.7 V to 1.9 V requirement.

Part Context

This part belongs to the Renesas low-power PCIe clock generator family. It serves as a fan-out buffer and frequency generator for high-speed serial interfaces. The device integrates phase-locked loop functionality to multiply the reference crystal frequency to the required PCIe clock rates.

Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas series. Verify electrical parameters such as jitter performance and output drive strength if substituting with other manufacturers' devices.
