9FGV0231AKILFT

Overview

The 9FGV0231AKILFT is a low-power PCI Express (PCIe) clock synthesizer manufactured by Renesas Electronics. It integrates a Phase-Locked Loop (PLL) to generate three output clocks from a single crystal input, supporting PCIe Gen1, Gen2, and Gen3 standards. The device operates at a maximum frequency of 100 MHz with a supply voltage range of 1.7V to 1.9V. It features HCSL and LVCMOS output drivers and is housed in a 24-VFQFPN package. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Integrated PLL for low-jitter clock synthesis
• Supports PCIe Gen1/Gen2/Gen3 applications
• Three differential or single-ended outputs
• Low power consumption with 1.8V supply

Applications

• PCI Express peripheral cards
• Server and storage backplanes
• Industrial control systems requiring precise timing

Procurement Notes

Verify the suffix 'AKILFT' corresponds to the specific tape-and-reel packaging and RoHS compliance status. Confirm the manufacturer's date code and lot traceability against the latest Product Change Notifications (PCNs). Ensure the ordering quantity matches the standard reel size of 2500 units if full reels are required, or verify cut-tape availability for smaller quantities.

Selection Notes

Select this model when a single-crystal input is required to drive multiple PCIe endpoints with low jitter. Compare the 1:3 input-to-output ratio against other variants like the 9FGV0441 (1:5 ratio) if more outputs are needed. Verify that the 1.8V supply voltage aligns with the system's power rails and that the -40°C to +85°C temperature range meets the environmental requirements.

Part Context

This component belongs to the 9FGV0231 family of low-power PCIe clock generators. It is functionally similar to the 9FGV0231AKLFT but may differ in packaging or compliance certifications. The 'A' suffix typically denotes an enhanced version or specific binning, while 'KILFT' indicates the lead-free, tape-and-reel packaging configuration.

Replacement Considerations

Direct pin-compatible replacements within the same family include the 9FGV0231AKLFT. For higher output counts, consider the 9FGV0441 series. Always verify electrical parameters such as jitter performance and supply voltage ranges before substituting.
