UG256: Si5383 Evaluation Board User s Guide The Si5383-EVB is used for evaluating the Si5383 Network Syn- EVB FEATURES chronizer Clock for SyncE/1588 and Stratum 3/3E applications. The Si5383 contains three independent DSPLLs in a single IC Powered from USB port or external +5 V with programmable jitter attenuation bandwidth on a per DSPLL power supply via screw terminals Onboard 48 MHz XTAL and included basis. The Si5383-EVB supports three independent differential SiOCXO1-EB reference board allows input clocks, two independent CMOS input clocks, and seven standalone or holdover mode of operation on the Si5383 independent output clocks via onboard SMA connectors. The CBPro GUI programmable V DDO Si5383-EVB can be controlled and configured via a USB connec- supplies allow each of the seven outputs tion to a host PC running Silicon Labs next generation Clock to have its own supply voltage selectable from 3.3, 2.5, or 1.8 V Builder Pro (CBPro) software tool. Test points are provided CBPro GUI allows control and on-board for external monitoring of supply voltages. measurement of voltage, current, and power of VDD and all 7 VDDO supplies Status LEDs for power supplies and control/status signals of Si5383 SMA connectors for input clocks, output clocks and optional external timing reference clock Skyworks Solutions, Inc.
