Si5347-D-EVB Si5347-D EVALUATION BOARD USERS GUIDE Description EVB Features The Si5347-D-EVB is used for evaluating the Si5347 Powered from USB port or external +5 V power Any-Frequency, Any-Output, Jitter-Attenuating Clock supply via screw terminals. Multiplier revision D. The device revision is Onboard 48 MHz XTAL allows standalone or distinguished by a white 1 inch x 0.187 inch label with holdover mode of operation on the Si5347. the text SI5347-D-EB installed in the lower left hand CBPro GUI programmable V supply allows DD corner of the board. (For ordering purposes only, the device supply voltages of 3.3, 2.5, or 1.8 V. terms EB and EVB refer to the board and the kit CBPro GUI programmable V supplies allow each DDO respectively. For the purpose of this document, the of the 8 outputs to have its own supply voltage terms are synonymous in context.) selectable from 3.3, 2.5, or 1.8 V. CBPro GUI allows control and measurement of voltage, current, and power of V and all 8 V DD 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. Figure 1.
