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
