9ZX21201BKLF

Overview

The Renesas 9ZX21201BKLF is a zero-delay buffer featuring one differential input and twelve HCSL outputs. It operates within a supply voltage range of 3.135V to 3.465V and supports frequencies up to 150MHz. The device is housed in a 64-VFQFPN package with dimensions of 9x9mm. Designed for Intel QPI and PCIe applications, it provides a 1:12 clock distribution ratio with differential signaling on both input and output sides.

Feature Summary

• 12-output HCSL buffer architecture
• Zero-delay configuration for low jitter
• Supports Intel QPI and PCIe standards

Applications

• Intel QuickPath Interconnect (QPI)
• PCI Express systems
• High-performance computing servers

Procurement Notes

Verify the specific ordering suffix BKLF against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with the 64-VFQFPN footprint during procurement planning.

Selection Notes

Select this component for designs requiring 12-channel HCSL distribution with zero-delay characteristics. Confirm that the 3.135V-3.465V supply range aligns with system power rails and that the 150MHz maximum frequency meets signal requirements.

Part Context

This part belongs to the Renesas Z-Buffer family, specialized for high-speed digital interfaces. It serves as a critical timing component for distributing reference clocks to multiple receivers in complex server architectures.

Replacement Considerations

Check for pin-compatible alternatives within the same Renesas series. Verify electrical parameters such as output drive strength and supply voltage tolerance before substituting.
