TS3USB3000: about eye pattern

Takashi Yamaguchi

Part Number: TS3USB3000

Hi team,

My customer is considering to use the TS3USB3000. Could you please help with the question below?

According to the data sheet, the crosstalk is -37dB at 240MHz. Can you give us an idea of whether the USB eye pattern is affected when one is communicating while the other is operating?

Regards,

Yamaguchi

Hi Brian-san,

Sorry to my unclear question.

For example,
While the D + / D- terminal and MHL + / MHL- are communicating,
when an equipment with a USB + / USB- terminal is inserted or removed,
effect on the communication waveform between D + / D- and MHL + / MHL-?

Or
While the D + / D- terminal and MHL + / MHL- are communicating
when the device of MHL + / MHL- terminal is removed,
impact on equipment connected to the USB + / USB-terminal.

Regards,

Yamaguchi

crosstalk -37db is pretty low for this application, we never heard any issue from customer
