    Hello,

    We’ve only tested cascading 2 522P devices. The major issue would be the turnaround time in USB which is set for a max cable length of 5m between devices. The only other limitation (Which is a bigger concern) would be keeping the VBUS voltage within spec over the cable length. There should not a limit on the number of 522Ps cascaded (In theory).

    Regards,
    Diego.

    Hi Diego,

    Thank you for your reply.

    I understand TI has tested only two 522Ps and some limitations of cascade connection.

    I am going to share these information with the customer.

    I appreciate your great help.

    Best regards,

    Shinichi
