Description
The Si5341-EVB is used for evaluating the Si5341 Low
Jitter Any-Frequency Clock Generator. The Si5341 uses
the patented Multisynth
technology to generate up to
10 independent clock frequencies each with 0 ppm
synthesis error. The Si5341-EVB has 3 independent
input clocks, an optional feedback input clock for zero
delay mode, and 10 independent output clocks. The
Si5341-EVB can be controlled and configured using the
Clock Builder Pro
(CB Pro
) software tool.
EVB Features
Powered from USB port or external power supply.
Onboard 48 MHz XTAL allows free-run mode of
operation on the Si5341 or up to 3 input clocks for
synchronous clocking.
Feedback clock input for optional zero delay mode.
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 10 outputs to have its own power supply
voltage selectable from 3.3, 2.5, or 1.8 V.
CBPro GUI-controlled voltage, current, and power
measurements of V
DD
and all V
DDO
supplies.
Status LEDs for power supplies and control/status
signals of Si5341.
SMA connectors for input and output clocks.
