PI6CB332016AZDEX-13R

Overview

The PI6CB332016A is a low-power PCIe 5.0/6.0 and PCIe 7.0 compatible clock buffer manufactured by Diodes Incorporated. It fans out a differential reference input into 16 low-power HCSL outputs, supporting frequencies up to 400 MHz with on-chip termination for 85Ω or 100Ω impedance. The device operates on a 3.3V supply (2.97V to 3.63V) within an industrial temperature range of -40°C to 105°C. Key features include individual output enables, Power Down Tolerant (PDT) support, automatic clock parking upon loss of signal, and flexible startup sequencing.

Feature Summary

• 16 Low-Power HCSL Outputs with On-Chip Termination
• Supports I/O Power Down Tolerant (PDT)
• Automatic Output Clock Parking Upon Loss of Input Clock
• Up to 9 Selectable SMBus Addresses

Applications

• PCIe 5.0 Applications
• PCIe 6.0 Applications
• PCIe 7.0 Applications

Procurement Notes

Verify the specific ordering suffix '-13R' against the manufacturer's official documentation to confirm packaging details such as tape and reel specifications. Ensure that the selected variant matches the required environmental and compliance standards for the target application.

Selection Notes

Select this component when designing systems requiring a single differential clock source to drive up to 16 downstream receivers at frequencies up to 400 MHz. Consider the integrated SMBus interface for dynamic output control and the PDT feature for power management requirements in high-speed serial link architectures.

Part Context

This part belongs to the PI6CB3320xx series of fanout clock buffers from Diodes Incorporated. It is specifically engineered for high-performance computing and networking infrastructure where low jitter and precise timing distribution are critical for maintaining data integrity across multiple lanes.

Replacement Considerations

Consult the manufacturer's cross-reference tools for verified alternatives. Ensure any substitute maintains compatibility with PCIe 5.0/6.0/7.0 jitter specifications and supports the same 64-pin V-QFN package dimensions.
