9ZXL1530DKILF - 15 to 19-Output Buffers

Description

The 9ZXL15x0D/9ZXL19x0D/9ZXL1951D devices comprise a family of 2nd-generation enhanced performance buffers for PCIe and CPU applications.

5 jitter specifications.

Devices are either 15 or 19 outputs.

Features

  • LP-HCSL outputs eliminate up to 4 resistors per output pair.
  • 9 selectable SMBus addresses.
  • Selectable PLL bandwidths minimizes jitter peaking in cascaded PLL topologies.
  • Hardware/SMBus control of ZDB and FOB modes allow change without power cycle.
  • 8 OE# pins support PCIe CLKREQ# functionality (9ZXL1951).
  • Spread spectrum compatible.
  • 100MHz and 133.33MHz ZDB mode (9ZXL15x0, 9ZXL19x0).
  • 100MHz ZDB mode (9ZXL1951).
  • 1.
  • 400MHz FOB mode (all devices).

15 to 19-Output Buffers for PCIe Gen1–5 and UPI 9ZXL15x0D/9ZXL19x0D/ 9ZXL1951D Datasheet Description The 9ZXL15x0D/9ZXL19x0D/9ZXL1951D devices comprise a family of 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 are either 15 or 19 outputs. The devices function as both fanout (FOB) and zero-delay (ZDB) buffers. All devices meet DB2000Q and DB1900Z jitter and skew requirements. Key Specifications ▪ ZDB Mode phase jitter: • PCIe Gen5 CC < 22fs RMS (Low Bandwidth) • QPI/UPI 11.
