Si5380-D Evaluation Board User s Guide The Si5380-D-EVB is used for evaluating the Ultra Low Jitter, Any- EVB FEATURES Frequency, 12-output JESD204B Clock Generator. The Si5380 Powered from USB port or external power employs fourth-generation DSPLL technology to enable clock gen- supply eration for LTE/ JESD204B applications which require the highest Onboard 54 MHz XTAL or Reference SMA level of jitter performance. The Si5380-D-EVB has four independ- Inputs allow holdover mode of operation on the Si5380 ent input clocks and a total of 12 outputs.
