9Z61195D - 19-Output DB1900Z Derivative

Description

The 9Z61195D is a second-generation, enhanced-performance DB1900Z derivative differential buffer.

The part is a pin-compatible upgrade to the 9Z61195A, offering much improved phase jitter performance.

A fixed external feedback maintains low drift for critical QPI/UPI applications.

Features

  • 19 Low-Power (LP) HCSL output pairs with 85Ω Zout Features.
  • LP-HCSL outputs with 85Ω Zout; eliminate 76 resistors, save 130mm2 of area.
  • SMBus OE bits; software control of each output.
  • 9 selectable SMBus addresses; multiple devices can share same SMBus segment.
  • Selectable PLL bandwidths; minimizes jitter peaking in cascaded PLL topologies.
  • Hardware/SMBus control of PLL bandwidth and bypass; change mode without power cycle.
  • Spread spectrum compatible; tracks sp.
