NOTICE - The following device(s) are recommended alternatives:

The 9DB423 is compatible with the Intel DB400Q Differential Buffer Specification. This buffer provides 4 PCI-Express SRC or 4 QPI clocks. The 9DB423 is driven by a differential output pair from a CK410B+ or CK509B 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
  • 50-140 MHz operation in PLL mode
  • 33-400 MHz operation in Bypass mode
