The 9DB403 is compatible the Intel DB400 Differential Buffer Specification v2.0. This buffer provides four PCI-Express SRC clocks. The 9DB403 is driven by a differential input pair from a CK409/CK410/CK505 main clock generator.

Features

  • 4- 0.7 V HCSL differential output pairs
  • Phase jitter: PCIe Gen2 < 3.1 ps rms
  • Phase jitter: PCIe Gen1 < 86 ps peak to peak
  • Supports zero delay buffer mode and fanout mode
  • Bandwidth programming available
  • 50-100 MHz operation in PLL mode
  • 50-400 MHz operation in Bypass mode
