The 9ZXL1550D is a second-generation enhanced-performance DB1900Z-derivative differential buffer. The part is a pin-compatible upgrade to the 9ZXL1550B, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications.

特長

  • LP-HCSL outputs with 85Ω Zout; eliminate 60 resistors, save 103mm² of area
  • PCIe Gen 1–5 compliance
  • 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
  • 9 x 9 mm 64-VFQFPN package; small board footprint
