9ZXL1951D - 19-Output DB1900ZL Derivative

Description

The 9ZXL1951D is a second-generation, enhanced performance DB1900ZL derivative buffer.

The part is a pin-compatible upgrade to the 9ZXL1951A, offering a much improved phase jitter performance.

Features

  • LP-HCSL outputs with 85Ω Zout; eliminates 76 termination resistors, saves 130mm2 area.
  • 8 OE# pins configurable to control up to 16 outputs; easy power management.
  • 9 selectable SMBus addresses; multiple devices can share same SMBus segment.
  • Selectabl.

19-Output DB1900ZL Derivative for PCIe Gen1–4 and QPI/UPI 9ZXL1951D Datasheet Description The 9ZXL1951D is a second-generation, enhanced performance DB1900ZL derivative buffer. The part is a pin-compatible upgrade to the 9ZXL1951A, offering a much improved phase jitter performance. It has 8 OE# pins that can be configured via SMBus to control up to 16 of the device's 19 outputs, and is packaged in a 6 x 6 mm QFN package for maximum space savings. A fixed external feedback maintains low drift for critical QPI/UPI applications.
