1 Si5395/94/92 data Sheet12-Channel, Any-Frequency, Any-Output Jitter Attenua-tor/Clock Multiplier with ultra -Low JitterThe Si5395/94/92 Jitter attenuators combine fourth-generation DSPLL and Multi-Synth technologies to deliver ultra -low jitter (69 fs) for high performance applica-tions like 56G SerDes. They are used in applications that demand the highest levelof integration and jitter performance. All PLL components are integrated on-chip,eliminating the risk of noise coupling associated with discrete solutions. Devicegrades J/K/L/M/E have an integrated reference to save board space, improve sys-tem reliability and reduces the effect of acoustic emissions noise caused by temper-ature ramps.

2 Grades A/B/C/D/P use an external crystal (XTAL) or crystal oscillator(XO) Si5395/94/92 support free-run, synchronous and holdover modes as well as en-hanced hitless switching, minimizing the phase transients associated when switch-ing between input clocks. These devices are programmable via a serial interfacewith in-circuit programmable non-volatile memory (NVM) so they always power upwith a known frequency configuration. Programming the Si5395/94/92 is easy withSkyworks ClockBuilderTM Pro software.
