Overview: DATA SHEET Si5361/Si5362/Si5363 18-Output, Any-Frequency, Any-Output Jitter Attenuators/Clock Multipliers with Ultra-Low Jitter Si5361/62/63 Jitter Attenuators combine fifth-generation DSPLL™ and MultiSynth™ technologies with an ultra-low jitter VCO to deliver ultra-low jitter (<55 fs) for high-performance applications like 112G and 224G SerDes and Coherent Optics. 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 two MultiSynths; the Si5362 has two DSPLLs with one MultiSynth, and the Si5363 has three DSPLLs. The Si5361H high-frequency variant targets optical module markets with output frequencies up to 2.75 GHz.
All devices support free-run, synchronous and holdover modes as well as enhanced hitless switching minimizing the phase transients associated when switching between input clocks. These devices are programmable via a serial interface with in-circuit programmable non-volatile memory (NVM) to enable powering up with a known frequency configuration.
Programming the Si5361/62/63 is easy with Skyworks ClockBuilderTM Pro (CBPro) software. The devices can be factory programmed allowing them to power up to known frequencies and settings or shipped as “blank” devices to give more flexibility.
