9FGV0641AKLF

Overview

The Renesas 9FGV0641AKLF is a single-circuit clock generator and PLL frequency synthesizer designed for PCI Express (PCIe) applications. It operates within a supply voltage range of 1.7V to 1.9V and supports a maximum output frequency of 100MHz. The device accepts LVDS or crystal inputs and provides HCSL and LVCMOS outputs in a 1:7 ratio. Packaged in a 40-VFQFN exposed pad, it functions within an operating temperature range of 0°C to 70°C.

Feature Summary

• Supports PCIe Gen 1/2/3 clock generation with zero-delay buffer functionality
• Accepts LVDS or crystal input sources for flexible system integration
• Provides seven outputs combining HCSL and LVCMOS signaling standards
• Operates on a low voltage supply of 1.7V to 1.9V

Applications

• PCI Express (PCIe) Riser Cards
• NVMe Storage Systems
• Networking Accelerators
• Industrial Control and Embedded Systems

Procurement Notes

Verify the specific package variant against the datasheet, as ordering suffixes may indicate different packaging types such as trays or reels. Confirm moisture sensitivity levels and lead-free status prior to procurement to ensure compliance with assembly requirements.

Selection Notes

Select this component when a single-channel PLL synthesizer is required for PCIe architectures. Ensure the design accommodates the 1.7V-1.9V supply rail and utilizes the available HCSL/LVCMOS output drivers. Verify that the 40-VFQFN footprint matches the PCB layout constraints.

Part Context

This part belongs to the 9FGV0641A series of intelligent PCIe clock buffers and generators. These devices are engineered to support Common (CC) and Independent Reference (IR) clocking architectures, making them suitable for complex multi-lane PCIe topologies requiring precise timing synchronization.

Replacement Considerations

Consult the manufacturer's official substitution guide for verified alternatives. Generic cross-references should be avoided due to potential differences in pinout configurations, electrical characteristics, and thermal performance specifications.
