9ZX21501C - FIFTEEN OUTPUT DIFFERENTIAL ZBUFFER

Description

The 9ZX21501C is a 15-output version of the Intel DB1900Z Differential Buffer suitable for PCI-Express Gen3 or QPI applications.

The part is backwards compatible to PCIe Gen1 and Gen2.

A fixed external feedback maintains low drift for critical QPI applications.

Features

  • 15 - 0.7V current mode differential HCSL output pairs Functional Block Diagram Features/Benefits.
  • Fixed feedback path; 0ps input-to-output delay.
  • 9 Selectable SMBus addresses; multiple devices can share same SMBus segment.
  • 7 dedicated OE# pins; hardware control of outputs.
  • PLL or bypass mode; PLL can dejitter incoming clock.
  • Selectable PLL BW; minimizes jitter peaking in downstream PLL's.
  • Spread spectrum compatible; tracks spreadin.
