PI6CB332001ZXBIEX

Clock Buffers, Drivers Overview

The PI6CB332001 is a 20-output PCIe Gen 4/Gen 5/Gen 6 clock buffer manufactured by Diodes Incorporated. It operates on a single 3.3V supply and accepts an HCSL input signal with frequencies up to 400MHz. The device provides 20 differential low-power HCSL outputs featuring integrated on-chip termination, eliminating the need for external resistors. Key electrical specifications include a maximum propagation delay of less than 3ns and output-to-output skew under 50ps. It supports SMBus control and a Side-Band Interface for individual output enable management.

Clock Buffers, Drivers Feature Summary

• Supports PCIe Gen 4, Gen 5, and Gen 6 standards with very low additive phase jitter (less than 30fs RMS for Gen 4/5).
• Features 20 differential HCSL outputs with built-in on-chip termination to simplify PCB layout.
• Offers dual output control methods: traditional OE# pins/SMBus or a 3-wire Side-Band Interface.
• Compliant with Intel DB2000QL specification and RoHS 3 directives.

Clock Buffers, Drivers Applications

• Distributing reference clocks for UPI, SAS, and SATA applications.
• PCIe Gen 4, Gen 5, and Gen 6 system designs requiring common clock architecture.
• High-performance server and storage infrastructure boards.

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel quantities. Confirm that the component meets the required environmental compliance standards, such as RoHS 3 and Halogen-free definitions, prior to finalizing procurement orders.

Clock Buffers, Drivers Selection Notes

Select this component when a high-fanout clock distribution solution is required for PCIe Gen 4 through Gen 6 systems. Ensure the design utilizes a 3.3V power rail and accommodates the 80-lead aQFN package dimensions. Verify that the input source can drive the specified HCSL input requirements up to 400MHz.

Clock Buffers, Drivers Part Context

This part belongs to the PI6CB33 series of clock buffers from Diodes Incorporated. It is designed as a successor or alternative to legacy Pericom clock distribution devices, specifically targeting modern high-speed serial interface standards like PCIe Gen 5 and Gen 6 which demand stricter jitter performance.
