9-output 1.8 V HCSL Fanout Buffer

The 9DBV0931 is a member of IDT's Full-Featured PCIe family. The device has 9 output enables for clock management, and 3 selectable SMBus addresses.

Features

  • LP-HCSL outputs; save 18 resistors and 31mm² compared to standard HCSL
  • 53mW typical power consumption; eliminates thermal concerns
  • Outputs can optionally be supplied from any voltage between 1.05 V and 1.8 V; maximum power savings
  • OE# pins; support DIF power management
  • HCSL-compatible differential input; can be driven by common clock sources
  • 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
  • 1 MHz to 200 MHz operating frequency
  • 3.3 V tolerant SMBus interface works with legacy controllers
  • Selectable SMBus addresses; multiple devices can easily share an SMBus segment
  • Device contains default configuration; SMBus interface not required for device operation
  • Space-saving 6x6 mm 48-pin VFQFPN; minimal board space
