Part Number: TUSB7340

Hi team,

Our customer want to know the max trace length of TUSB7340 for USB 2.0 and USB 3.0. 

Their design is:

Main board trace length: USB 2.0 < 3 inches and USB 3.0 < 4 inches 

Cable length: 400 mm

Control board trace length: less than 1.5 inches

Is their design OK?

    Hello Naizeng,

    Those lengths are within standard USB recommendations, but please be aware that the TUSB7340 is Not Recommended for New Designs and support is limited to existing documentation only.
