Part Number: TUSB2E22

Hello TI team

The MacPro typec receptacle USB2.0 can only work A6 A7 or B6 B7 that mean when the device directly insert receptor the A6 A7 PIN work USB 2.0 ,and flipping insert receptor B6 B7 PIN work USB 2.0, so use the TUSB2E22 can cross the USB 2.0 signal . But the TUSB2E22 is eUSB to USB, Now I am looking for cross signal device USB 2.0 to USB 2.0 , will you can recommend some part number.

below  is the  system  diagram .

  • Hi,

    Please look through the USB 2.0 passive switches / muxes for an appropriate device.  This one may work for your application:

    Hello JMMN

    thanks for your quickly reply !

    follow your recommend , the system block will be like the below diagram . It maybe doesn’t fit the design .

    When use two TS3USB221E to cross signal , it doesn’t the good signal chain . Can you share some design?

    below is update the system diagram

    Can you share some information on what type of board is between the two type-c receptors?  Many Type C applications simply tie the two DP pins together and the two DM pins together so switching is not required.  Depending on the application you may want to implement a USB 2.0 redriver like the TUSB216 to boost the signal.

    Hi JMMN:

    The right typec receptor is  connect the MacPro or other host , the left receptor is connect the dock .

    My final target is use the cross signal PCBA simulation the DOCK insert  flipping or  not flipping .

    I had select the TUSB1064 to cross the TX RX signal PIN . now it also need the cross the USB2.0 signal .

    It is a Type-C requirement to mux the USB 3.x signals, but the USB 2.0 signals can just be shorted so regardless of cable orientation the USB 2.0 lines are always connected, unless you would prefer to mux them?

  • In reply to JMMN:

    If there is appropriate device. I prefer the MUX .

    Hi,

    We do not have a single device USB 2.0 cross point so the application would have to use either two 2:1 muxes back to back or short the USB 2.0 lines on one of the connectors.

    we will have an USB2 Crosspoint Mux later this year .
