The 9ZML1253E is a second generation enhanced performance DB1200ZL derivative. The part is a pin-compatible
upgrade to the 9ZML1232B, while offering a much improved phase jitter performance. A fixed external feedback maintains low drift for critical QPI/UPI applications, while each input channel has software adjustable input-to-output delay to ease transport delay management for today's more complex server topologies. The 9ZML1253E has an SMBus Write Lockout pin for increased device and system security.

特長

  • SMBus write lock feature; increases system security
  • 2 software-configurable input-to-output delay lines; manage transport delay for complex topologies
  • LP-HCSL outputs with 85Ω Zout; eliminate 48 resistors, save 82mm² of area
  • 12 OE# pins; hardware control of each output
  • 3 selectable SMBus addresses; multiple devices can share same SMBus segment
  • Selectable PLL bandwidths; 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
  • 10 x 10 mm 72-VFQFPN package; small board footprint
