Hardware Overview and Setup Power the EVB by applying a 3.0 to 5.5 V dc supply to terminal block J1. The isolated output is available at terminal block J2. Test points for these are available at the upper edge of the EVB. The default EVB configuration has the header JP13 shorted, so the dc-dc output powers the VDDB supply (U1 pin 19) of the Si88241ED-IS. The acceptable input voltage to the VDDB supply pin is 3.0 to 5.5 V. If the user chooses to generate an output voltage outside this voltage range, the jumper at JP13 must be removed and a separate supply source connected to VDDB through JP13. To measure input supply current, clip a differential probe across JP12 to access each side of sense resistor R20. The SH input (U1 pin 7) disables the dc-dc converter function. Install a jumper across JP9 to pull the SH input high and disable the dc-dc converter. If interfacing to an external controller board through the JP9 header, the controller must drive SH low for normal operation and high to disable the dc-dc. The EVB has a series of headers for connecting to each digital channel. The inside conductor of each 2x1 header is connected to the device pin and the outer conductor is tied to ground through a protection resistor. Connect to each side of the Si88xxxISO-EVB to external controllers through a two-row ribbon cables with one row grounded. 2 Skyworks Solutions, Inc. • Phone [781] 376-3000 • Fax [781] 376-3100 • sales@skyworksinc.com • www.skyworksinc.com Rev. 0.2 • Skyworks Proprietary Information • Products and Product Information are Subject to Change Without Notice • December 21, 2021 2 UG232: Si88xxxISO-EVB User's Guide • Si88xxxISO-EVB Schematics 2.
