Si5395/94/92 Jitter Attenuators Skyworks Solutions Inc. Si5395/94/92 Jitter Attenuators combine fourth-generation DSPLL™ and Multi-Synth™ technologies to deliver ultra-low phase jitter. These attenuators provide enhanced hitless switching that minimizes output phase transients with a typical value of 0.2ns. The Si5395/94/92 jitter attenuators support the free run, synchronous, and holdover modes of operation and offer both automatic and manual input clock switching. These attenuators are programmable via a serial interface with in-circuit programmable Non-Volatile Memory (NVM). The Si5395/94/92 jitter attenuators can be easily programmed with Skyworks Solutions Inc. ClockBuilder Pro™ software. These attenuators find their applications in Optical Transport Network (OTN) muxponders and transponders, 56G/112G PAM4 SerDes clocking, and medical imaging.
