SKYWORKS SI5347A-D11350-GM

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 Skyworks' ClockBuilder Pro software. Factory preprogrammed devices are also available.
