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

 (CB Pro

)

software tool.

EVB Features

Powered from USB port or external power supply.

Onboard 48 MHz XTAL or Reference SMA Inputs 
allow holdover mode of operation on the Si5345.

CBPro

 GUI programmable V

DD

 supply allows 

device to operate from 3.3, 2.5, or 1.8 V.

CBPro GUI programmable V

DDO

 supplies allow each 

of the 10 outputs to have its own power supply 
voltage selectable from 3.3, 2.5, or 1.8 V.

CBPro GUI-controlled voltage, current, and power 
measurements of V

DD

 and all V

DDO

 supplies.

Status LEDs for power supplies and control/status 
signals of Si5345.

SMA connectors for input clocks, output clocks, and 
optional external timing reference clock.
