    Hi, McKenzie

    Thank you for support.

    I have an additional question regarding the contents of the USB Interface (app note) provided in the link above.

    Q1) For 10Gbps, TPD4E02B04 (4CH) x 1ea was used for Tx, Rx, but is there a special reason for using TPD1E01B04 (1CH) x 4ea for 20Gbps?

    Q2) Looking at Table 6-1, TPD4E02B04 is recommended for D+, D-, TX/RX for 10-Gbps per lane. Is it applicable only for 10Gbps or less??

     

    Please check. Thank you.

    Hi Grady, 

    To answer your first question, we didn't want to show the same option for multiple USB speeds. This way it shows someone an option with a 1 4-channel device and an option with 4 1-channel devices. 

    TPD4E02B04 can support up to 20Gbps but that is the maximum it can support. I believe the 1- Gbps per lane is listed because USB 3.2 2x2 has 2 lanes with each being 10Gbps. 

    Best,
