Hi John,

7000 mil is acceptable for TUSB1002A however the quality of the layout can cause a large variation in performance. Please see the app note below on tips for high speed layout guide lines. Please keep the number of vias in the data path to a minimum. The maximum length will always vary with the layout quality and application (external noise).
