ECMF02-2HSMX6 can also be used for USB 2.0. On datasheet, fig 13 and 14 give USB 2.0 eye diagram with and without part, to show that it is OK for USB 2.0, and to show that impact on eye diagram is very low.

Hi,
Can ECMF02-2AMX6 used for USB 3.0 application.
Can you also confirm how many pins have inbuilt ESD diode? According to datasheet its 4. But according to diagram in datasheet 4 pins have ESD

Hi,

ECMF02-2AMX6 is dedicated to USB 2.0, and it was not tested for USB 3.0.

For USB 3.0, we recommend:

  • for 1 pair, ECMF02-2HSMX6
  • for 2 pairs, ECMF04-4HSWM10, or ECMF4-2450A60N10

For USB 2.0 and USB 3.0, I recommend ECMF02-2HSMX6.

Regards.
