Description
EVB Features
The Si5347-EVB is used for evaluating the Si5347
Quad Any-Frequency Jitter Attenuating Clock Multiplier.
The Si5347 contains 4 independent DSPLLs in a single
IC with programmable jitter attenuation bandwidth on a
per DSPLL basis. The Si5347-EVB supports 4
independent input clocks and 8 independent output
clocks via on-board SMA connectors. The Si5347-EVB
can be controlled and configured via a USB connection
to a host PC running Silicon Labs’ next generation
Clock Builder Pro (CBPro) software tool. Test points
are provided on-board for external monitoring of supply
voltages.
 Powered from USB port or external +5 V power
supply via screw terminals.
 Onboard 48 MHz XTAL allows standalone or
holdover mode of operation on the Si5347.
 CBPro GUI programmable V_DD supply allows
device supply voltages of 3.3, 2.5, or 1.8 V.
 CBPro GUI programmable V_DDO supplies allow each
of the 8 outputs to have its own 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 8 V_DDO
supplies.
 Status LEDs for power supplies and control/status
signals of Si5347.
 SMA connectors for input clocks, output clocks and
optional external timing reference clock.
