9ZXL1950D - 19-Output DB1900ZL Low-Power Derivative
Pin-to-pin with improved performance
The 9ZXL1950 is a DB1900Z derivative buffer utilizing Low-Power HCSL (LP-HCSL) outputs to increase edge rates on long traces, reduce board space, and reduce power consumption more than 50% from the original 9ZX21901.It is pin-compatible to the 9ZXL1930 and fully integrates the output terminations. It is pin-compatible to the 9ZXL1930 and fully integrates the output terminations. It is suitable for PCI-Express Gen1/2/3 or QPI/UPI applications, and uses a fixed external feedback to maintain low drift for demanding QPI/UPI applications.

Features

  • 19 - LP-HCSL Differential Output Pairs w/integrated terminations (Zo = 85Ω)
  • LP-HCSL outputs; up to 90% IO power reduction, better signal integrity over long traces
  • Direct connect to 85Ω transmission lines; eliminates 76 termination resistors, saves 130mm² area
  • Pin compatible to the 9ZXL1930; easy upgrade to reduced board space
  • 72-VFQFPN package; smallest 19 output Z-buffer
  • Fixed feedback path; ~0ps input-to-output delay
  • 9 Selectable SMBus addresses; multiple devices can share same SMBus segment
  • Separate VDDIO for outputs; allows maximum power savings
  • PLL or bypass mode; PLL can dejitter incoming clock
  • 100MHz & 133.33MHz PLL mode; legacy QPI support
  • Selectable PLL BW; minimizes jitter peaking in downstream PLL's
  • Spread spectrum compatible; tracks spreading input clock for EMI reduction
  • SMBus Interface; unused outputs can be disabled
