The Si5396 is a dual DSPLL version with either multiple time domains 4 outputs or 12 outputs. Each DSPLL has access to any of the four inputs and can Ultra-low phase jitter of 95 fs rms provide low jitter clocks on any of the device outputs. Device grades J/K/L/M have an Enhanced hitless switching minimizes integrated reference to save board space, improve system reliability and reduces the output phase transients effect of acoustic emissions noise caused by temperature ramps.
