Si5348-D Evaluation Board User s Guide The Si5348-D-EVB is used for evaluating the Si5348 Network EVB FEATURES Synchronizer Clock for SyncE/1588 and Stratum 3/3E applica- tions. The device revision is distinguished by a white 1 inch Powered from USB port or external +5 V x 0.187 inch label with the text SI5348-D-EB in the lower power supply via screw terminals Included SiOCXO1-EB reference OCXO left-hand corner of the board. (For ordering purposes only, the board allows for evaluation in standalone terms EB and EVB refer to the board and the kit respectively. and holdover mode. In this document, the terms are synonymous in context.) The CBPro GUI programmable VDD supply allows device supply voltages from 3.3, Si5348 contains three independent DSPLLs in a single IC with 2.5, or 1.8 V programmable jitter attenuation bandwidth on a per DSPLL basis. CBPro GUI programmable V supplies DDO The Si5348-D-EVB supports three independent differential input allow each of the seven outputs to have its own supply voltage selectable from 3.3, clocks, two independent CMOS input clocks, and seven inde- 2.5, or 1.8 V pendent output clocks via onboard SMA connectors. The Si5348- CBPro GUI allows control and measurement of voltage, current, and D-EVB can be controlled and configured via a USB connection power of VDD and all 8 VDDO supplies to a host PC running Silicon Labs next generation ClockBuilder Status LEDs for power supplies and Pro (CBPro) software tool. Test points are provided on-board for control/status signals of Si5348 SMA connectors for input clocks, output external monitoring of supply voltages. clocks and optional external timing reference clock The device revision is distinguished by a white 1 inch x 0.187 inch label with the text SI5348-D-EB installed in the lower left hand corner of the board.
