9ZX21501

15-output DB1900Z Derivative

The 9ZX21501 is an Intel DB1900Z-compatible Differential Buffer suitable for PCIExpress 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 HCSL differential output pairs
  • 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
  • Supports zero delay buffer mode and fanout mode
  • Bandwidth programming available
  • 9 selectable SMBus Addresses
  • 7 OE# pins90-140 MHz operation in PLL mode
  • 33-150 MHz operation in Bypass mode
