9ZXL0631EKILFT

Overview

The 9ZXL0631EKILFT is a DB600ZL OEM derivative clock buffer from Renesas Electronics, designed for Intel QPI and PCI Express (PCIe) applications. It features one circuit with a 1:6 input-to-output ratio, supporting differential HCSL inputs and outputs. The device operates at a maximum frequency of 400MHz with a supply voltage range of 3.135V to 3.465V. Integrated PLL functionality supports low-jitter performance. It is housed in a 40-VFQFPN (5x5mm) package with an exposed pad, suitable for surface mount installation across an operating temperature range of -40°C to 85°C.

Feature Summary

• DB600ZL OEM derivative optimized for Intel QPI and PCIe systems
• 1:6 fanout ratio with differential HCSL input/output signaling
• Integrated PLL for jitter reduction in high-speed clock distribution
• Operates within 3.135V–3.465V supply voltage and -40°C to 85°C temperature range

Applications

• Intel QuickPath Interconnect (QPI) clock distribution
• PCI Express (PCIe) system clock buffering
• High-performance computing server backplanes
• Network infrastructure timing modules

Procurement Notes

Verify the specific ordering suffix EKILFT against official Renesas documentation to confirm packaging type and moisture sensitivity level. Ensure compatibility with existing board layouts regarding the 40-VFQFPN footprint and thermal pad requirements. Cross-reference electrical specifications with the target system's clock domain requirements before procurement.

Selection Notes

Select this component when a 1:6 differential HCSL fanout is required for Intel QPI or PCIe architectures. The integrated PLL makes it suitable for applications needing jitter attenuation. Compare against the standard 9ZXL0651 series if generic availability is preferred, noting that this SKU represents a specific OEM derivative variant with potentially distinct qualification status.

Part Context

This part belongs to the 9ZXL family of zero-delay and fanout buffers by Renesas. It serves as an OEM-specific derivative of the DB600ZL architecture, tailored for high-frequency clock distribution in data center and enterprise networking equipment. It complements other members like the 9ZXL0831 and 9ZXL1231 by offering a six-output configuration in a compact 5x5mm package.

Replacement Considerations

The 9ZXL0651EKILFT is a direct functional equivalent within the same product family. Verify pinout compatibility and ensure the replacement part meets the same Intel QPI/PCIe compliance standards.
