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 are blocked until PLL is locked; clean system start-up
  • Device contains default configuration; SMBus interface is not required for device control
  • 3.3V tolerant SMBus interface works with legacy controllers
  • Space-saving 24-pin 4mm x 4mm VFQFPN; minimal board space
