Hello everyone, I´m working on a PCB Design including TUSB7320 and I´m using "TUSB73x0 Board Design and Layout Guidelines". NEar to USB connectors there are Common Mode Chokes TDK TCE_1210 (Obsolete). I have read that this component is only used when there are EMI problems. Are they necessary for the design? Which component is recommended as substitute?
Thank you so much.
