The Si5361/62/63 Jitter Attenuators combine fifth-generation DSPLL™ and MultiSynth™ technologies with an high performance VCO to deliver ultra-low jitter (<55 fs) for high-performance. They are used in applications that demand the highest level of integration and jitter performance. All PLL components are integrated on-chip, eliminating the risk of noise coupling associated with discrete solutions. The Si5361 has a single-DSPLL with 2 MultiSynths, the Si5362 has 2-DSPLLs with 1 MultiSynth and the Si5363 has 3-DSPLLs. The Si5361H high frequency variant is capable of output frequencies up to 2.75 GHz targeting the optical module and line card markets.
