PI6CB332001ZXBIEX-13R

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 up to 400 MHz, typically 100 MHz. The device provides 20 differential low-power HCSL outputs with integrated on-chip termination, eliminating the need for external resistors. Key electrical specifications include a maximum propagation delay of 3 ns, output-to-output skew under 50 ps, and very low additive phase jitter compliant with PCIe Gen 1 through Gen 6 standards. It supports industrial operating temperatures from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports Intel DB2000QL specification and PCIe Gen 1/2/3/4/5/6 standards
• 20 differential low-power HCSL outputs with on-chip termination
• Dual control modes: Traditional OE# pins/SMBus or 3-wire Side-Band Interface
• Very low additive phase jitter (<30fs RMS for Gen 4/5, <16fs RMS for Gen 6)

Clock Buffers, Drivers Applications

• Distributing reference clocks for UPI (Ultra Path Interconnect)
• SAS (Serial Attached SCSI) clock distribution
• SATA (Serial ATA) clock distribution
• PCIe Gen 4/5/6 system designs

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape-and-reel quantity. Confirm RoHS compliance status and lead-free definitions as per Diodes Incorporated quality definitions before procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a high-fanout clock buffer with integrated termination is required for PCIe Gen 4, 5, or 6 systems. Ensure the design utilizes the 80-lead 6x6mm dual-row aQFN package constraints. Verify that the 3.3V supply voltage range (3.135V to 3.465V) aligns with the system power rails.
