Si5348/83/84/88/89 Network Synchronizer Clocks

The Silicon Labs network synchronizer clocks lead the industry in jitter performance while offering low power consumption. With up to three integrated DSPLL® devices and small package sizes, these devices reduce complexity and PCB footprint requirements for timing synchronization. Our network synchronizer clocks are ideally suited for SyncE/SONET/SDH timing card and pizza box applications, as well as wireless communication systems and data center switches.   

Each DSPLL is individually configurable as a SyncE/SONET/SDH PLL, IEEE 1588 DCO with support for 1PPS/1Hz, or a general-purpose PLL for processor or FPGA clocking. Legacy SETS systems can also use these devices to achieve  Stratum 3/3E compliance. 

The Si5388/89 clock has embedded IEEE 1588 servo loop processing and when combined with the available IEEE 1588 host software stack, it forms a complete IEEE 1588 synchronization solution for pizza box applications, wireless 5G communication systems, and data center switches.
