Description
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.
EVB Features
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.
