Si5386 Evaluation Board User's Guide
The Si5386E-E-EB is used for evaluating the Ultra Low Jitter, Any-
Frequency, 12-output JESD204B Clock Generator. The Si5386
employs fourth-generation DSPLL technology to enable clock gen-
eration for LTE/ JESD204B applications which require the highest
level of jitter performance. The Si5386E-E-EB has four independ-
ent input clocks and a total of 12 outputs. The Si5386E-E-EB can
be easily controlled and configured using Silicon Labs' Clock
Builder Pro™ (CBPro™) software tool.
The device revision is distinguished by a white 1 inch x 0.187 inch label with the text
"Si5386E-E-EB" installed in the lower left hand corner of the board. (For ordering purpo-
ses only, the terms "EB" and "EVB" refer to the board and the kit respectively. For the
purpose of this document, the terms are synonymous in context.)
