9ZX21200BKLF

Overview

The Renesas Electronics 9ZX21200BKLF is a high-performance zero-delay buffer (ZDB) designed for Intel QPI and PCI Express applications. It features one differential HCSL input driving twelve differential outputs, operating at frequencies up to 150 MHz. The device requires a supply voltage between 3.135 V and 3.465 V and functions within an ambient temperature range of 0°C to +70°C. Packaged in a 56-VFQFN exposed pad (8x8 mm), it integrates a PLL for jitter reduction while maintaining low drift through fixed feedback paths suitable for demanding system topologies.

Feature Summary

• 1:12 differential output ratio with HCSL signaling
• Integrated PLL for clock de-jittering
• Supports Intel QPI and PCIe standards
• 56-VFQFN package for compact board layout

Applications

• Intel QuickPath Interconnect (QPI)
• PCI Express (PCIe) systems
• High-performance server clock distribution

Procurement Notes

Verify the specific ordering suffix BKLF against official Renesas documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with the required 3.135V to 3.465V supply voltage range during procurement planning.

Selection Notes

Select this component when a single differential clock source must drive twelve downstream loads with minimal skew. Confirm that the 56-VFQFN footprint fits the PCB design constraints and that the 150 MHz maximum frequency meets the system timing requirements.

Part Context

This part belongs to the Renesas Z-Buffer family, specialized for zero-delay buffering in high-speed digital interfaces. It serves as a critical timing element in server architectures requiring precise clock synchronization across multiple components.

Replacement Considerations

Consult Renesas datasheets for pin-compatible alternatives within the 9ZX series. Verify electrical parameters such as supply voltage and output drive strength before substituting.
