Si5342-D-EVB Si5342-D EVALUATION BOARD USERS GUIDE Description EVB Features The Si5342-D-EVB is used for evaluating the Si5342 Powered from USB port or external power supply. Any-Frequency, Any-Output, Jitter-Attenuating Clock Onboard 48 MHz XTAL or Reference SMA Inputs Multiplier revision D. The device revision is allow holdover mode of operation on the Si5342. distinguished by a white 1 inch x 0.187 inch label with ClockBuilder Pro (CBPro) GUI programmable V DD the text SI5342-D-EB installed in the lower left hand supply allows device to operate from 3.3, 2.5, or corner of the board. (For ordering purposes only, the 1.8 V. terms EB and EVB refer to the board and the kit CBPro GUI programmable V supplies allow each respectively. For the purpose of this document, the DDO terms are synonymous in context.) 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 and all 4 V DD 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. Figure 1.
