8-Output Differential Buffer for PCIe Gen 1

9DB108 Datasheet
NOTICE - The following device(s) are recommended alternatives:
9DBL0841 - 8-Output 3.3V PCIe Zero-Delay/Fanout Clock Buffer9DBL0851 - 8-Output 3.3V PCIe Zero-Delay/Fanout Clock Buffer9DB803 - 8-output Differential Buffer for PCIe Gen2

Overview

The 9DB108 8-output differential buffer for PCIe Gen 1 is not recommended for new designs. The 9DB803 8-output differential buffer for PCIe Gen 2 is the recommended replacement.

  • Supports tight ppm accuracy clocks for Serial-ATA
  • Spread spectrum modulation tolerant, 0% to -0.5% down spread and ± 0.25% center spread
  • Supports undriven differential output pair in PD# and SRC_STOP# for power management
