Part Number: TUSB212


Hi Team,

It's found that sometimes the amplitude of high speed signal suddenly becomes larger which leads to the disconnection, could you please help analysis the possible reasons?

Thanks and Best Regards!

    Hi Hao,

    It seems that this disconnect is cause by a signal reflection. These reflections are mostly caused impedance mis-match. Can you give details on the test setup and procedure? Is TUSB212 enabled in this test? It does not seem that the AC boost is enabled.
