Description

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’ ClockBuilder Pro software. Factory preprogrammed devices are also available.
