PI6CB332001AZXBIEX-13R

Clock Buffers, Drivers Overview

The PI6CB332001A is a 20-output PCIe clock buffer supporting 1.0 through 6.0 standards, designed for distributing reference clocks in UPI, SAS, and SATA applications. It accepts an HCSL input signal with a typical frequency of 100MHz and a maximum of 400MHz. The device provides 20 differential low-power HCSL outputs featuring integrated on-chip termination to eliminate external resistors. Operating at a nominal 3.3V supply voltage, it delivers very low additive phase jitter, meeting stringent PCIe specifications across multiple generations.

Clock Buffers, Drivers Feature Summary

• Supports Intel DB2000QL specification with PCIe 1.0/2.0/3.0/4.0/5.0/6.0 compliance
• Features 20 differential HCSL outputs with built-in on-chip termination
• Offers dual control modes: traditional OE# pins/SMBus or a 3-wire Side-Band Interface
• Delivers ultra-low differential additive phase jitter (e.g., <16fs RMS for PCIe 6.0)

Clock Buffers, Drivers Applications

• UPI (Universal Processing Interconnect) reference clock distribution
• SAS (Serial Attached SCSI) system clock generation
• SATA controller clock buffering

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'R' against the manufacturer's documentation to confirm tape-and-reel packaging details. Ensure the selected variant matches the required industrial temperature range of -40°C to +85°C. Confirm RoHS and halogen-free compliance status prior to integration.

Clock Buffers, Drivers Selection Notes

Select this component when a high-channel-count clock distribution solution is required for PCIe-based architectures. The integrated termination simplifies PCB layout by removing the need for 80 external resistors. Consider the Side-Band Interface if dynamic output control via a serial protocol is preferred over discrete GPIO pins.
