Description
The Si5342-EVB is used for evaluating the Si5342
Any-Frequency, Any-Output, Jitter-Attenuating Clock
Multiplier. The Si5342 combines 4th generation DSPLL
and Multisynth
technologies to enable any-frequency
clock generation for applications that require the highest
level of jitter performance. The Si5342-EVB can be
controlled and configured using the ClockBuilder Pro
(CB Pro
) software tool.
EVB Features
Powered from USB port or external power supply.
Onboard 48 MHz XTAL or Reference SMA Inputs
allow holdover mode of operation on the Si5342.
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 Si5342.
SMA connectors for input clocks, output clocks, and
optional external timing reference clock.
