Silicon Laboratories Si5383-EVB User Manual

UG256: Si5383 Evaluation Board User's
Guide
The Si5383-EVB is used for evaluating the Si5383 Network Syn-
chronizer Clock for SyncE/1588 and Stratum 3/3E applications.
The Si5383 contains three independent DSPLLs in a single IC
with programmable jitter attenuation bandwidth on a per DSPLL
basis. The Si5383-EVB supports three independent differential
input clocks, two independent CMOS input clocks, and seven in-
dependent output clocks via onboard SMA connectors. The
Si5383-EVB can be controlled and configured via a USB connec-
tion to a host PC running Silicon Labs' next generation Clock
Builder Pro™ (CBPro™) software tool. Test points are provided
on-board for external monitoring of supply voltages.
