Si5340-EVB Si5340 EVALUATION BOARD USERS GUIDE Description Features The Si5340-EVB is used for evaluating the Si5340 Low Powered from USB port or external power supply Jitter Any-Frequency Clock Generator. The Si5340 uses Onboard 48 MHz XTAL allows free-run mode of TM the patented Multisynth technology to generate up to operation on the Si5340 or up to 3 input clocks for 10 independent clock frequencies each with 0 ppm synchronous clocking synthesis error. The Si5340-EVB has 3 independent Feedback clock input for optional zero delay mode input clocks, an optional feedback input clock for zero TM CBPro GUI-programmable VDD supply allows delay mode, and 4 independent output clocks. The device to operate from 3.3, 2.5, or 1.8 V. Si5340-EVB can be controlled and configured using the TM TM CBPro GUI-programmable VDDO supplies allow Clock Builder Pro (CB Pro ) software tool. each of the 4 outputs to have its own supply voltage selectable from 3.3, 2.5, or 1.8 V CBPro GUI-controlled voltage, current, and power measurements of VDD and all VDDO supplies.
