The 9ZXL1252E is a second-generation, enhanced-performance DB1200ZL differential buffer. The part is a pin-compatible upgrade to the 9ZLX1252A, while offering a much improved phase jitter performance and an SMBus Write Lock feature for increased system security. A fixed external feedback maintains low drift for critical QPI/UPI applications. The 9ZXL1252E has an SMBus Write Lockout pin for increased device and system security.

Features

  • SMBus write lock feature; increases system security
  • PCIe Gen 1–5 compliance
  • LP-HCSL outputs with 85Ω Zout; eliminate 48 resistors, save 82mm² of area
  • 12 OE# pins; hardware 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
  • 100MHz and 133.33MHz PLL mode; UPI and legacy QPI support
  • 9 x 9 mm 64-QFN package; small board footprint
