9ZXL0652EKILF

Overview

The 9ZXL0652EKILF is a clock buffer from Renesas Electronics designed for high-speed serial interfaces. It features a single circuit with one input and up to twelve outputs, supporting frequencies up to 400MHz. The device utilizes HCSL output signaling and includes an integrated PLL. It operates on a supply voltage ranging from 3.135V to 3.465V and functions within a temperature range of -40°C to 85°C. The component is housed in a 40-VFQFPN (5x5) surface-mount package.

Feature Summary

• Supports up to twelve differential outputs for fanout applications
• Integrates a phase-locked loop for signal conditioning
• Includes SMBus write protect functionality for configuration security

Applications

• Intel QuickPath Interconnect (QPI)
• PCI Express (PCIe) Gen1 through Gen7 systems
• Ultra Path Interconnect (UPI)

Procurement Notes

Verify the specific suffix EKILF against current Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage requirements of 3.135V to 3.465V. Confirm that the 40-VFQFPN footprint matches the design layout. Check for any recent product change notices regarding manufacturing location or material composition updates.

Selection Notes

Select this component when designing systems requiring distribution of clock signals to multiple PCIe or QPI endpoints. The integrated PLL allows for jitter reduction compared to passive buffers. The SMBus interface enables dynamic configuration and protection. Ensure the application supports the specified HCSL output swing and frequency limits.

Part Context

This part belongs to the 9ZXL series of clock generators and buffers optimized for server and storage applications. It complements other variants like the 9ZXL0852E and 9ZXL1251 by offering a specific output count and package combination. The series targets high-performance computing environments requiring reliable clock distribution across multiple lanes.

Replacement Considerations

Consult official substitution lists for direct pin-compatible alternatives within the 9ZXL family. Verify if variants such as the 9ZXL0652E without the suffix meet the same electrical specifications. Cross-reference datasheets to ensure identical output drive strength and packaging dimensions before replacement.
