Si5392-97 and Si5342-47 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/J/K/L/M) any-frequency jitter attenuating clocks generates any output frequency up 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/E) offers 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 superior stability over temperature ramps and offer PCB space savings.
