Overview: Si5345/44/42 Rev D Data Sheet 10-Channel, Any-Frequency, Any-Output Jitter Attenuator/Clock Multiplier
These jitter attenuating clock multipliers bine 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 Skyworks’ ClockBuilder Pro™ software. Factory preprogrammed devices are also available.
Applications: • OTN muxponders and transponders • 10/40/100 G networking line cards • GbE/10 GbE/100 GbE Synchronous Ethernet (ITU-T G.8262) • Carrier Ethernet switches • SONET/SDH line cards • Broadcast video • Test and measurement • ITU-T G.
