JAJSKH4A April 2022 – May 2024 TUSB1104
PRODUCTION DATA
The USB 3.2 standard requires all host, hubs, and devices support USB polarity inversion detection and correction. For this reason, polarity between TUSB1104 and USB connector as well as between USB Host/Device and TUSB1104 does not have to be maintained. Not maintaining polarity will simplify layout by eliminating the need to swap P and N in the layout. The Figure 6-1 shows example in which polarity between USB host and redriver is not maintained.
