9.2.2 Detailed Design Procedure

TUSB2E22 has four loss compensation settings for high speed operation and proper setting should be selected to match the system loss profile to optimize jitter performance. USB 2.0 high speed eye diagram measurements could be used as a guide to confirm the loss compensation is optimum for a given system.
