9ZX21501BKLF

Overview

The Renesas Electronics Corporation 9ZX21501BKLF is a single-circuit Intel QPI and PCI Express (PCIe) fanout buffer and multiplexer. It features a 1:15 input-to-output ratio with differential HCSL signaling on both input and output. The device operates at a maximum frequency of 400MHz and includes an integrated PLL. It requires a supply voltage between 3.135V and 3.465V and functions within an operating temperature range of 0°C to 70°C. The component is housed in a 64-VFQFN package with an exposed pad, measuring 9x9mm.

Feature Summary

• Supports Intel QPI and PCIe applications with 1:15 distribution ratio
• Features differential HCSL input and output signaling
• Integrated PLL for clock generation and buffering
• Operates at frequencies up to 400MHz

Applications

• Intel QuickPath Interconnect (QPI) systems

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type and material specifications. Ensure compatibility with the required 64-VFQFN footprint and exposed pad thermal requirements during procurement planning.

Selection Notes

Select this component for designs requiring a single differential clock input to drive fifteen HCSL outputs. Confirm that the system power supply remains within the 3.135V to 3.465V range and that the ambient temperature stays within the 0°C to 70°C operational limits.

Part Context

This part belongs to the 9ZX series of high-performance clock buffers designed by Renesas. It serves as a critical timing element in high-speed digital interfaces, specifically optimizing signal integrity for QPI and PCIe protocols through its dedicated architecture and low-jitter performance characteristics.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical parameters carefully when considering equivalent devices from other manufacturers.
