5-output 1.8 V HCSL Fanout Buffer with Zo=100 ohms

The 9DBV0541 is a member of IDT's Full-Featured PCIe family. The device has 5 output enables for clock management, and 3 selectable SMBus addresses. It has integrated terminations for direct connection to 100ohm transmission lines.

Features

  • 100ohm direct connect; saves 20 resistors and 34mm² compared to standard HCSL
  • 50mW typical power consumption; eliminates thermal concerns
  • OE# pins; support DIF power management
  • HCSL-compatible differential input; can be driven by common clock sources
  • Spread Spectrum Compatible; allows EMI reduction
  • SMBus-selectable features allow optimization to customer requirements
    • Slew rate for each output; allows tuning for various line length
    • 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 5x5 mm 32-pin VFQFPN; minimal board space
