UG335: Si5395 Evaluation Board User's
Guide
The Si5395 EVB is used for evaluating the Si5395 Any-Frequency, Any-Output, Jitter-
Attenuating Clock Multiplier. There are two different EVBs for the Si5395. There is a
Grade A and a Grade P board. This user guide is intended for both versions of the
Si5395 EVBS. The device grade and revision is distinguished by a white 1 inch x 0.187
inch label installed in the lower left hand corner of the board. In the example below, the
label "SI5395A-A-EB" indicates the evaluation board has been assembled with an
Si5395 device, Grade A, Revision A, installed. (For ordering purposes only, the terms
“EB” and “EVB” refer to the board and the kit, respectively. For the purpose of this docu-
ment, the terms are synonymous in context.)
