The 9ZXL0451 is a second generation enhanced performance DB800ZL derivative for PCIe Gen4 and 5 applications. In fanout (bypass) mode, it is DB2000Q compatible. A fixed external feedback in ZDB mode maintains low drift for critical QPI/UPI.
 

Features

  • LP-HCSL outputs eliminate 16 resistors; save 32mm2 of area
  • PCIe Gen 1–5 compliance
  • 4 OE# pins; SMBus control also available
  • 3 selectable SMBus addresses
  • 2 selectable ZDB bandwidths; minimizes jitter peaking in cascaded PLL topologies
  • Hardware/SMBus control of ZDB bandwidth and fanout modes
  • Spread spectrum compatible
  • 100MHz ZDB mode
  • 5 × 5 mm 32-VFQFPN package; small board footprint
