2-output 1.8 V PCIe Gen1/2/3 Zero Delay / Fanout Buffer

The 9DBV0231 is a member of IDT's 1.8V Very-Low-Power (VLP) PCIe family.  The device has 2 output enables for clock management.

Features

  • LP-HCSL outputs; save 4 resistors compared to standard HCSL outputs
  • 35mW typical power consumption in PLL mode; minimal power consumption
  • Spread Spectrum (SS) compatible; allows use of SS for EMI reduction
  • OE# pins; support DIF power management
  • HCSL compatible differential input; can be driven by common clock sources
  • SMBus-selectable features; optimize signal integrity to application
    • slew rate for each output
    • differential output amplitude
  • Pin/software selectable PLL bandwidth and PLL Bypass; minimize phase jitter for each application
  • Outputs blocked until PLL is locked; clean system start-up
  • Device contains default configuration; SMBus interface not required for device control
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Space saving 24-pin 4x4mm VFQFPN; minimal board space
