Si5392/5394/5395/5396/5397 Clock Jitter Attenuators, Jitter Cleaners

The Silicon Labs jitter attenuators lead the industry in jitter performance and frequency flexibility. Designed to meet the exacting specifications and high-performance requirements of Internet infrastructure, these best-in-class, ultra-low jitter clock devices reduce cost and complexity for a wide range of timing applications.  

The Si539x (A/B/C/D) any-frequency jitter attenuating clocks generate output frequency (100 Hz to 1028 MHz) from any input frequency (8 kHz to 750 MHz), yet still deliver industry-leading jitter performance (90-fs RMS phase jitter). The Si5395/4/2 (P) offers the best in class jitter (69-fs RMS phase jitter) for ultra-high performance applications like 56G/112G SerDes. Our innovative architecture combines proprietary DSPLL® and MultiSynth technologies, providing infinite frequency synthesis and jitter attenuation in a highly integrated PLL solution.
