Description
The Si5342-D-EVB is used for evaluating the Si5342
Any-Frequency, Any-Output, Jitter-Attenuating Clock
Multiplier revision D. The device revision is
distinguished by a white 1 inch x 0.187 inch label with
the text “SI5342-D-EB” installed in the lower left hand
corner of the board. (For ordering purposes only, the
terms “EB” and “EVB” refer to the board and the kit
respectively. For the purpose of this document, the
terms are synonymous in context.)
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.

Errata:
"LOSXAXBB" silkscreen is missing from Si5342-EB REV 3.1.
D5, D7, D8, D14, D15, D16, and D17 are status LEDs indicating the device alarms currently asserted. D11 is
illuminated when USB +5 V supply voltage is present. D12 and D13 are status LEDs showing on-board MCU
activity.
