9ZXL1950D - 19-Output DB1900Z Derivative

This page provides the datasheet information for the 9ZXL1950D, a member of the 9ZXL1930D 19-Output DB1900Z Derivative family.

Datasheet Summary

Description

The 9ZXL1930D / 9ZXL1950D are second-generation, enhanced-performance DB1900Z-derivative differential buffers.

The parts are pin-compatible upgrades to the 9ZXL1930B and 9ZXL1950B, while offering a much improved phase jitter performance.

Features

  • 19 Low-Power HCSL (LP-HCSL) output pairs (1930D).
  • 19 Low-Power HCSL (LP-HCSL) output pairs with 85Ω Zout (1950D) Features.
  • LP-HCSL outputs; eliminate 38 resistors, save 65mm2 of area (1930D).
  • LP-HCSL outputs with 85Ω Zout; eliminate 76 resistors, save 130mm2 of area (1950D).
  • SMBus OE bits; software control of each output.
  • 9 selectable SMBus addresses; multiple devices can share the same SMBus segment.
  • Selectable PLL BW; minimizes jitter peaking in cascaded PL.

19-Output DB1900Z Derivative 9ZXL1930D / 9ZXL1950D for PCIe Gen1–4 and UPI Datasheet Description The 9ZXL1930D / 9ZXL1950D are second-generation, enhanced-performance DB1900Z-derivative differential buffers. The parts are pin-compatible upgrades to the 9ZXL1930B and 9ZXL1950B, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications. In fanout mode, the devices meet the DB2000Q additive phase jitter specification.
