Description
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.
EVB Features
Powered from USB port or ex5 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.
