Si5380 Evaluation Board User's Guide
The Si5380-EVB is used for evaluating the Ultra Low Jitter, Any-
Frequency, 12-output JESD204B Clock Generator. The Si5380
employs 4th generation DSPLL technology to enable clock gen-
eration for LTE/ JESD204B applications which require the high-
est level of jitter performance. The Si5380-EVB has four inde-
pendent input clocks and a total of 12 outputs. The Si5380-EVB
can be easily controlled and configured using Silicon Labs’ Clock
Builder Pro™ (CBPro™) software tool.
