Features

  • LP-HCSL outputs; save 10 resistors and 17mm² compared to standard HCSL
  • PCIe Gen 1–5 compliance
  • 50mW typical power consumption; eliminates thermal concerns
  • OE# pin for each output; support DIF power management
  • HCSL differential input; can be driven by common clock sources
  • Spread spectrum tolerant; allows reduction of EMI
  • SMBus-selectable features allow optimization to customer requirements
    • Slew rate for each output; allows tuning for various line lengths
    • Differential output amplitude; allows tuning for various application environments
  • 1MHz to 200MHz operating frequency
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Selectable SMBus addresses; multiple devices can easily share an SMBus segment
  • Device contains default configuration; SMBus interface is not required for device operation
  • Space saving 32-pin 5mm x 5mm VFQFPN; minimal board space

Description

The 9DBV0531 5-output 1.8V PCIe fanout clock buffer has five output enables for clock management and three selectable SMBus addresses.
