The 9DBU0231 is a member of IDT's 1.5 V Ultra-Low-Power (ULP) PCIe family. The device has 2 output enables for clock management.

Features

  • LP-HCSL outputs; save 4 resistors compared to standard HCSL outputs.
  • 35 mW typical power consumption in PLL mode; minimal power consumption
  • OE# pins; support DIF power management
  • HCSL-compatible differential input; can be driven by common clock sources
  • LP-HCSL differential clock outputs; reduced power and board space
  • Programmable slew rate for each output; allows tuning for various line lengths
  • Programmable output amplitude; allows tuning for various application environments
  • Pin/software selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
  • Outputs blocked until PLL is locked; clean system start-up
  • Configuration can be accomplished with strapping pins; SMBus interface not required for device control.
  • 3.3 V tolerant SMBus interface  works with legacy controllers
  • Space-saving 4x4 mm 24-pin VFQFPN; minimal board space
