9DBL08

8-output 3.3V PCIe Zero-Delay Buffer

The 9DBL08 devices are 3.3V members of IDT’s Full-Featured PCIe family. The 9DBL08 supports PCIe Gen1-4 Common Clocked (CC) and  PCIe Separate Reference Independent Spread (SRIS) systems. It offers a choice of integrated output terminations providing direct connection to 85Ω or 100Ω transmission lines. The 9DBL08P1 can be factory programmed with a user-defined power up default SMBus configuration.
 
For information regarding evaluation boards and material, please contact your local IDT sales representative.

Features

  • PCIe Gen1-2-3-4 CC compliant in ZDB mode
  • PCIe Gen2 SRIS compliant in ZDB mode
  • Supports PCIe Gen2-3 SRIS in fan-out mode
  • Supports PCIe SRnS clocking in ZDB or fan-out mode
  • Direct connection to 100Ω (xx42) or 85Ω (xx52) transmission lines; saves 32 resistors compared to standard PCIe devices
  • Spread Spectrum tolerant; allows reduction of EMI
  • Pin/SMBus selectable selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
  • Device contains default configuration; SMBus interface not required for device operation.
  • Easy AC-coupling to other logic families, see IDT application note AN-891.
  • Space saving 48-pin 6x6mm VFQFPN; minimal board space
