SILICON LABS SI5344A-B03291-GM

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. Furthermore, 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.
