Description
EVB Features
The Si5346-EVB is used for evaluating the Si5346
Any-Frequency, Any-Output, Jitter-Attenuating Clock
Multiplier. The Si5346 contains 2 independent DSPLLs
in a single IC with programmable jitter attenuation
bandwidth on a per DSPLL basis. The Si5346-EVB
supports 4 independent input clocks and 4 independent
clock outputs via on-board SMA connectors. The
Si5346-EVB can be controlled and configured using the
ClockBuilderPro (CBPro) software tool. Test points
are provided on-board for external monitoring of supply
voltages.
 Powered from USB port or external power supply.
 Onboard 48 MHz XTAL allows standalone or
holdover mode of operation on the Si5346.
 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 4 outputs to have its own power supply
voltage selectable from 3.3, 2.5, or 1.8 V.
 CBPro GUI allows control and measurement of
voltage, current, and power of V_DD and all 4 V_DDO
supplies.
 Status LEDs for power supplies and control/status
signals of Si5346.
 SMA connectors for input clocks, output clocks, and
optional external timing reference clock.
