The 9ZXL1930D is a second-generation, enhanced-performance DB1900Z-derivative differential buffer. The part is a pin-compatible upgrade to the 9ZXL1930B, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.

Features

  • LP-HCSL outputs; eliminate 38 resistors, save 65mm² of area
  • 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 PLL topologies
  • Hardware/SMBus control of PLL bandwidth and bypass; change mode without power cycle
  • Spread spectrum compatible; tracks spreading input clock for EMI reduction
  • 10 x 10 mm 72-VFQFPN package; small board footprint
