9ZXL0651AKLF

Overview

The Renesas 9ZXL0651AKLF is a single-circuit clock buffer integrated circuit featuring an internal Phase-Locked Loop (PLL). Designed for Intel QPI and PCI Express applications, it accepts a differential HCSL clock input and provides six differential outputs. The device operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 400MHz. It is housed in a 40-VFQFPN package with dimensions of 5x5 mm and includes an exposed pad for thermal management. The component functions within an industrial temperature range of 0°C to 70°C.

Feature Summary

• Six differential outputs with HCSL signaling
• Internal PLL for jitter reduction
• Supports Intel QPI and PCIe standards
• 40-VFQFPN (5x5) surface mount package

Applications

• Intel QuickPath Interconnect (QPI)
• PCI Express (PCIe) systems
• High-speed data transmission interfaces

Procurement Notes

Verify the specific suffix 'AKLF' against official Renesas documentation to confirm the exact operating temperature grade and packaging details. Ensure compatibility with the required 3.135V to 3.465V power supply rails during system design validation.

Selection Notes

Select this component when a low-jitter clock distribution solution is required for Intel QPI or PCIe architectures. Confirm that the 400MHz maximum frequency meets the system requirements and that the 0°C to 70°C operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the 9ZXL series of zero-delay clock buffers from Renesas Electronics. These devices are engineered to provide precise clock signal distribution with minimal skew and jitter, making them suitable for high-performance computing and communication infrastructure requiring strict timing integrity.

Replacement Considerations

Consult the official Renesas product selection guide for direct pin-to-pin replacements within the 9ZXL family. Verify that alternative models support the same 1:6 ratio, HCSL output type, and 40-VFQFPN package form factor.
