9ZXL1251E - 4 to 12-Output Buffers

Download the 9ZXL1251E datasheet PDF. This datasheet also covers the 9ZXL1231E variant, as both devices belong to the same 4 to 12-output buffers family and are provided as variant models within a single manufacturer datasheet.

Description

The 9ZXL04x1E/9ZXL06x1E/9ZXL08x1E/9ZXL12x1E family of Zero-Delay/Fanout Buffers (ZDB, FOB) are 2nd-generation enhanced performance buffers for PCIe and CPU applications.

5 jitter specifications.

Features

  • 4.
  • 12 Low-power HCSL (LP-HCSL) outputs.
  • Integrated terminations eliminate up to 4 resistors per output pair.
  • Dedicated OE# pins support PCIe CLKREQ# function.
  • Up to 9 selectable SMBus addresses (9ZXL12).
  • Selectable PLL bandwidths minimizes jitter peaking in cascaded PLL topologies.
  • Hardware/SMBus control of ZDB and FOB modes.
  • Spread-spectrum compatible.
  • 1.
  • 400MHz FOB operation (all devices).
  • 100MHz and 133.33MHz ZDB mode (9ZXL12, 9ZXL08.

4 to 12-Output Buffers for PCIe Gen1–5 and UPI 9ZXL04x1E/9ZXL06x1E/ 9ZXL08x1E/9ZXL12x1E Datasheet Description The 9ZXL04x1E/9ZXL06x1E/9ZXL08x1E/9ZXL12x1E family of Zero-Delay/Fanout Buffers (ZDB, FOB) are 2nd-generation enhanced performance buffers for PCIe and CPU applications. The family meets all published QPI/UPI, DB2000Q and PCIe Gen1–5 jitter specifications. Devices range from 4 to 12 outputs, with each output having an OE# pin to support the PCIe CLKREQ# function for low power states. All devices meet DB2000Q, DB1200ZL and DB800ZL jitter and skew requirements.
