Si5397

Si5397/96 Data Sheet Dual/Quad DSPLL™ Any-Frequency, Any-Output Jitter Attenuators The Si5397 is a high-performance, 8-output jitter-attenuating clock multiplier which integrates four any-frequency DSPLLs for applications that require maximum integration and independent timing paths. The Si5396 is a dual DSPLL version with either 4 outputs or 12 outputs. Each DSPLL has access to any of the four inputs and can provide low jitter clocks on any of the device outputs. Device grades J/K/L/M have an integrated reference to save board space, improve system reliability and reduces the effect of acoustic emissions noise caused by temperature ramps. Grades A/B/C/D use an external crystal (XTAL) or crystal oscillator (XO) reference. Based on 4th generation DSPLL technology, these devices provide any-frequency conversion with typical jitter performance of 95 fs. Each DSPLL supports independent free-run, holdover modes of operation, as well as automatic and hitless input clock switching. The Si5397/96 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 Si5397/96 is easy with Silicon Labs' ClockBuilderTM Pro software. Factory pre-programmed devices are also available.
