Description
EVB Features
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.
 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.
