Description

The Si5347 is a high performance jitter attenuating clock multiplier which integrates four

any-frequency DSPLLs for applications that require maximum integration and independent

timing paths. The Si5346 is a dual DSPLL version in a smaller package. Each DSPLL has

access to any of the four inputs and can provide low jitter clocks on any of the device

outputs. Based on 4th generation DSPLL technology, these devices provide any-frequency

conversion with typical jitter performance under 100 fs. Each DSPLL supports independent

free-run, holdover modes of operation, as well as automatic and hitless input clock

switching. The Si5347/46 is programmable via a serial interface with in-circuit

programmable non-volatile memory so that it always powers up in a known configuration.

Programming the Si5347/46 is easy with Silicon Labs’ ClockBuilder Pro software. Factory

pre-programmed devices are also available.
