Si531x/2x/6x/7x Clock Jitter Attenuators

The Silicon Labs jitter attenuators, jitter cleaners generate infinite combinations of low-jitter output frequencies from any input frequency. Based on our innovative third generation DSPLL® architecture, these devices simplify clock tree design by replacing multiple clocks and oscillators, thereby minimizing bill of materials count and complexity. 



Features

  • Generates any frequency on any output(2 kHz - 1.4 GHz)
  • Ultra-low jitter: 300 fs RMS
  • Integrated loop filter with selectable loop bandwidth
  • Hitless switching with phase buildout (auto/manual)
  • Synchronous and freerun modes
  • Best-in-class PSRR
  • Dynamically reconfigurable output frequency (per output)
  • Fast-lock: <100 ms
  • Serially programmable via I²C/SPI
