Part Number:TS3USB221A

Hi all,

 Four TS3USB221A are used on one board , as shown in the figure below, there will be three kinds of data streams: A, B and C.

What is the main impact of four chips cascade and how to  improve layout design?

USB0 and USB1 are two USB ports of MCU. For red line, Normally USB0 is used to connect micro-USB or connect-1. Micro-usb is mainly used for debug. Connect-1 is used to connect USB cameras. For green line, usb1 is connected to data module.

For yellow line, tt is used to connect module with computer.
