概要

The 9ZXL0831 is a low-power 8-output differential buffer that meets all the performance requirements of the Intel DB800ZL specification. It is suitable for PCI Express Gen 1/2/3 or QPI/UPI applications and uses fixed external feedback to maintain low drift for demanding QPI/UPI applications.

9ZXL0831 - Pinout
  • 8 - 0.7V low-power HCSL-compatible output pairs
  • Low-power push-pull outputs; Save power and board space - no Rp
  • Space-saving 48-pin VFQFPN package
  • Fixed feedback path for 0ps input-to-output delay
  • 8 OE# pins; hardware control of each output
  • PLL or bypass mode; PLL can de-jitter incoming clock
  • 100MHz or 133MHz PLL mode operation; supports PCIe and QPI applications
  • Selectable PLL bandwidth; minimizes jitter peaking in downstream PLLs
  • Spread spectrum compatible; tracks spreading input clock for low EMI
  • Cycle-to-Cycle jitter <50ps
  • Output-to-Output skew <65 ps
  • Input-to-Output delay variation <50ps
  • PCIe Gen 3 phase jitter <1.0ps RMS
  • QPI/UPI 9.6GT/s 12UI phase jitter <0.2ps RMS
