The 9ZXL1951D is a second-generation, enhanced performance DB1900ZL derivative buffer. The part is a pin-compatible upgrade to the 9ZXL1951A, offering a much improved phase jitter performance. It has 8 OE# pins that can be configured via SMBus to control up to 16 of the device's 19 outputs, and is packaged in a 6 x 6 mm QFN package for maximum space savings. A fixed external feedback maintains low drift for critical QPI/UPI applications.

特性

  • LP-HCSL outputs with 85Ω Zout; eliminates 76 termination resistors, saves 130mm² area
  • PCIe Gen 1–5 compliance
  • 8 OE# pins configurable to control up to 16 outputs; easy power management
  • 9 selectable SMBus addresses; multiple devices can share 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
  • 100MHz PLL mode; UPI support
  • DIF input and DIF outputs on outer row of pins; easy board routing
  • 6 x 6 mm dual-row 80-GQFN; smallest 19-output Z-buffer
