Si5392-97 and Si5342-47 Jitter Attenuators, Jitter Cleaners

Our jitter attenuators use DSPLL® and MultiSynth technology to deliver best-in-class jitter cleaning. They are able to deliver any combination of output frequencies.  

The Si539x (A/B/C/D/J/K/L/M) any-frequency jitter attenuating clocks generate any output frequency up to 1028 MHz from any input frequency (8 kHz to 750 MHz), while delivering industry-leading jitter performance. Si5395/4/2 (P/E) devices offer the best-in-class jitter (69-fs RMS phase jitter) for ultra-high performance applications like 56G/112G SerDes. The Integrated Reference variants (J/K/L/M/E) offer better reliability and superior stability over temperature ramps and offer PCB space savings.

Output frequency
Up to 1028 MHz
Phase jitter (RMS)
90 fs
