PI6CB332013AZLFEX-13R

Overview

The PI6CB332013AZLFEX-13R is a low-power PCIe 5.0/6.0 fanout clock buffer manufactured by Diodes Incorporated. It features one differential HCSL input and thirteen differential HCSL outputs, supporting frequencies up to 400 MHz with on-chip termination for 85Ω or 100Ω impedance. The device operates on a single 3.3V supply (2.97V to 3.63V) within an industrial temperature range of -40°C to 105°C. Key electrical characteristics include a typical propagation delay of 3 ns, output skew under 50 ps, and extremely low additive phase jitter suitable for high-speed serial interfaces.

Feature Summary

• Thirteen low-power HCSL outputs with selectable 85Ω or 100Ω on-chip termination
• Additive phase jitter as low as 3 fs RMS for PCIe 6.0 applications
• Flexible control via individual OE# pins, SMBus interface, and Side-Band Interface (SBI)
• Supports Power Down Tolerant (PDT), automatic clock parking upon LOS, and flexible startup sequencing

Applications

• PCI Express 5.0 and 6.0 reference clock distribution
• High-performance server and storage systems requiring low-jitter clocking
• Multi-lane interconnect architectures needing synchronized clock fanout

Procurement Notes

Verify the specific suffix 'ZLFEX-13R' against official documentation to confirm packaging details such as tape-and-reel quantity and orientation. Ensure the ordering information matches the required RoHS compliance and lead-free status specified in the datasheet. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when designing systems requiring a 1:13 fanout ratio for PCIe Gen 5 or Gen 6 clocks. Ensure the design supports the 3.3V supply voltage and accommodates the 56-VQFN package dimensions. Consider the need for SMBus or SBI control if dynamic output enablement or configuration is required during operation.

Part Context

This part belongs to the PI6CB3320xx series of low-power clock buffers from Diodes Incorporated. It is specifically engineered for high-speed serial link applications, offering superior jitter performance compared to standard clock buffers. The ZLF designation indicates a lead-free, halogen-free green package compliant with environmental directives.

Replacement Considerations

Consult the manufacturer's official substitution guide for verified alternatives. Generic pin-compatible replacements may not match the specific jitter performance or SMBus/SBI register map required for PCIe 6.0 compliance.
