Description  
Multi  
Synth  
These jitter attenuating clock multipliers combine fourth-generation DSPLL and  
MultiSynth™ technologies to enable any-frequency clock generation and jitter  
attenuation for applications requiring the highest level of jitter performance. These  
devices are programmable via a serial interface with in-circuit programmable non-  
volatile memory (NVM) so they always power up with a known frequency configuration.  
They support free-run, synchronous, and holdover modes of operation, and offer both  
automatic and manual input clock switching. The loop filter is fully integrated on-chip,  
eliminating the risk of noise coupling associated with discrete solutions. Further, the  
jitter attenuation bandwidth is digitally programmable, providing jitter performance  
optimization at the application level. Programming the Si5345/44/42 is easy with  
Silicon Labs’ ClockBuilderPro software. Factory preprogrammed devices are also  
available.
