PI6CB332008AZLFEX-13R

Overview

The PI6CB332008AZLFEX-13R is an 8-output low-power fanout clock buffer designed for PCIe 5.0, 6.0, and 7.0 applications. It accepts a differential HCSL input and provides eight differential HCSL outputs with on-chip termination selectable for 85Ω or 100Ω impedance. The device operates at frequencies up to 400MHz with a supply voltage range of 2.97V to 3.63V. Key features include individual output enables, Power Down Tolerance (PDT), automatic clock parking upon loss of signal, and support for SMBus and Side-Band Interface (SBI) control. It is housed in a 40-pin VQFN package.

Feature Summary

• Supports PCIe 5.0/6.0/7.0 standards with additive phase jitter as low as 3fs RMS for PCIe 6.0
• Eight differential HCSL outputs with selectable 85Ω or 100Ω on-chip termination
• Individual active-low output enable pins for flexible power management
• Power Down Tolerant (PDT) inputs and automatic output clock parking upon input loss

Applications

• PCIe 5.0/6.0/7.0 compliant system designs
• High-speed server and storage backplanes
• Network infrastructure equipment requiring low-jitter clock distribution

Procurement Notes

Verify the specific ordering suffix '13R' against Diodes Incorporated documentation to confirm tape-and-reel quantity and packaging specifications. Ensure the required output impedance configuration (85Ω vs 100Ω) matches the selected variant within the PI6CB332008A family.

Selection Notes

Select this component when designing systems requiring up to 400MHz clock distribution for next-generation PCIe interfaces. Consider the 40-VQFN package dimensions and thermal requirements. Verify compatibility with the host controller's SMBus or SBI interface capabilities for dynamic output control.

Part Context

This part belongs to the PI6CB332008A series from Diodes Incorporated. The base model PI6CB332008A defines the core electrical characteristics, while the suffix indicates specific packaging or impedance variants. It serves as a critical timing element for distributing reference clocks to multiple endpoints in high-bandwidth architectures.

Replacement Considerations

Direct replacements must match the 8-output HCSL architecture and 400MHz frequency limit. Verify pin-to-pin compatibility if substituting with other 40-pin VQFN clock buffers. Check that alternative devices support the same PDT and SMBus/SBI control protocols.
