Si5345 E
VALUATION
Description
The Si5345-EVB is used for evaluating the Si5345
Any-Frequency, Any-Output, Jitter-Attenuating Clock
Multiplier. The Si5345 combines 4th generation DSPLL

and Multisynth technologies to enable any-frequency
clock generation for applications that required the
highest level of jitter performance. The Si5345-EVB has
4 independent input clocks and 10 independent output
clocks. The Si5345-EVB can be controlled and
configured using the Clock Builder Pro
software tool.
