9ZXL0652EKILFT

Overview

The 9ZXL0652EKILFT is a differential buffer clock generator manufactured by Renesas Electronics. It provides six outputs with a 1:6 input-to-output ratio, designed for Intel QPI and PCI Express applications. The device operates at a maximum frequency of 400MHz and accepts spread spectrum input. It utilizes an HCSL output format and features a built-in PLL. The component is housed in a 40-VFQFN exposed pad package, measuring 5x5mm, and supports surface mount installation. It functions within a supply voltage range of 3.135V to 3.465V and operates across a temperature range of -40°C to 85°C.

Feature Summary

• Provides six differential outputs for zero-delay fanout distribution
• Accepts spread spectrum input signals for noise reduction
• Integrates a Phase-Locked Loop (PLL) for precise clock generation
• Optimized for high-speed interface standards including PCIe and QPI

Applications

• PCI Express (PCIe) clock distribution systems
• Intel QuickPath Interconnect (QPI) architectures
• High-performance server and workstation motherboards
• Network infrastructure equipment requiring low-jitter timing

Procurement Notes

Verify the specific suffix EKILFT against current Renesas documentation to confirm package type and tape/reel specifications. Check for any Product Change Notifications (PCNs) regarding assembly location or material composition updates. Ensure compatibility with existing board layouts due to the 40-VFQFPN footprint. Confirm end-of-life status or obsolescence notices prior to finalizing procurement plans.

Selection Notes

Select this component when a single differential input must be distributed to six differential loads with minimal skew. The integrated PLL allows for frequency multiplication up to 400MHz. Consider the 40-pin VFQFN package constraints for thermal management and PCB space. Verify that the HCSL output swing matches the receiver requirements of the target PCIe or QPI components.

Part Context

This part belongs to the 9ZXL series of clock generators from Renesas, specifically the 9ZXL06x2E family. These devices are engineered for demanding data center and communication applications. The 9ZXL0652 variant specifically offers a 1:6 fanout configuration, distinguishing it from other ratios in the same product line such as 1:1 or 1:12 options.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Potential alternatives may include other 1:6 differential fanout buffers from Renesas or competitors like IDT, provided they match the 400MHz speed, HCSL output, and 40-VFQFN package dimensions.
