TUSB522P: Can TUSB522P fully pass the USB compliance test ?

Part Number: TUSB522P


Hello Team,

Please allow me to ask you about TUSB522P.

Our customer is considering to use USB 3.0 repeater which can pass USB3.0 compliance test for their system.
They will only choose a proven device which could fully pass the test. 

Q1) Can TUSB522P fully pass USB compliance test specs for USB 3.0/3.1 ?

Q2). If YES, could you please share us the test result data and the test setup which used for the compliance testing ?

Best Regards,

Kawai

    Hello kawai,


        The TUSB522P passes the USB3.1 & 3.0 compliance test, using the EVM and the setup described by the USBIF for the compliance test procedure. The electrical tests are irrelevant for the customer since the EQ configuration depends on the layout implementation however, I can share with you the CV test results that were the weak point in our previous re-driver generations. The fails you can see on the CV test sections are generated by the device and not the re-driver (the result is the same with and without TUSB522P), and the reason is that the device attached is gen 3.0 meanwhile, the CV test tool was expecting a gen 3.1 device.
