The Si5386 is a high performance, integer and fractional clock generator for wireless applications which demand the highest level of integration and phase noise performance. Based on Silicon Laboratories’ 4th generation DSPLL technology, the Si5386 combines frequency synthesis and jitter attenuation in a highly integrated digital solution that eliminates the need for external VCXO and loop filter components. A fixed frequency crystal that provides frequency stability for free-run and holdover modes is integrated within the package saving valuable PCB space. This all-digital solution provides superior performance that is highly immune to external board disturbances such as power supply noise.

Modern C-RAN remote radio heads and fixed wireless systems require a diverse set of clocks such as ADC/DAC, RF LOs, eCPRI/CPRI, and Ethernet clocks. The Si5386 architecture is designed to deliver high-performance JESD204B DCLK and SYSREF clock pairs and flexible any-rate clocks for non-LTE clocks such as Ethernet and system reference clocks all from a single IC.
