Other Parts Discussed in Thread: TUSB211

Hi Team

We didn't see any PCB length requirement for TUSB211 per-channel and post-channel in the datasheet? Could you be able to provide the related information?

    Hello Kerr,

    We don't have a trace length spec because this device improves the signal's slew-rate but does not compensate the DC loss, so it is highly dependent on the trace and cable quality. What we recommend as a first approach is to have the TUSB211 close to the connector when the trace is about 12 inches ; if the trace is longer than that you can include an extra re-driver at the beginning of the USB traces.

    Regards,
    Diego.
