Part Number: TUSB215
Other Parts Discussed in Thread: TUSB551,

Hi, 

My customer is going to have USB related design.

(For USB2.0: TUSB215,  For USB3.0: TUSB551)

Please help to provide comments for the following questions:

1. For USB2.0: TUSB215, what is the max drive transmission distance ,and the suggested cable material and test data which can meet the max drive transmission distance

2. For USB3.0: TUSB551, what is the max drive transmission distance ,and the suggested cable material and test data which can meet the max drive transmission distance

Thanks.

    Hi Mike,

    Could you give some details about your application? It is hard to give specific max transmission distances as it depends on the transmission media used in your application . One key factor to understand of your chosen transmission media is the insertion loss. 

    In general, TUSB215 can help to compensate for USB cables up ~4m as measured at the far end. TUSB551 can help to compensate up to 9 dB of loss in the pre-channel and 6 dB of loss in the post-channel. Quality of the PCB layout will also effect the performance of both devices.
