Overview

Description

The 9ZX21901C is an Intel DB1900Z Differential Buffer suitable for PCI Express Gen1-2-3 or QPI applications. The 9ZX21901C has a fixed external feedback path. See the 9ZX21901B for an adjustable external feedback path. 

Features

  • 19 - 0.7V HCSL differential output pairs
  • Fixed external feedback path
  • Phase jitter: PCIe Gen3 < 1ps rms
  • Phase jitter: PCIe Gen2 < 3.1ps rms
  • Phase jitter: PCIe Gen1 < 86ps peak to peak
  • Phase jitter: QPI 9.6GT/s < 0.2ps rms
  • PLL or bypass mode
  • PLL can dejitter incoming clock
  • 9 selectable SMBus Addresses
  • 8 OE# pins
  • 100MHz or 133MHz PLL mode operation for PCIe and QPI applications
  • Selectable PLL bandwidth minimizes jitter peaking in downstream PLL's
