Part Number: TPD4E02B04-Q1
We will be using the FTDI FT601 chip to do the interfacing to the USB 3.0 bus. In our previous USB 2.0 design FTDI recommended also PulseGuard ESD Suppressors - PGB1010603 on the USB 2.0 DP/DM signals as well as 10pF Caps to GND. When I asked them about this requirement for this design using the FT601 they claimed that it was NOT necessary as a different PHY is being used. When I looked at the data sheet for the FT601 ESD and Latch-up Specifications :-
Human Body Mode (HBM) - JEDEC EIA/JESD22- A114-B, Class 2 - ±2kV
Machine mode (MM) - JEDEC EIA/JESD22- A115-A, Class B - ±200V
Charged Device Mode (CDM) - JEDEC EIA/ JESD22-C101- D, Class-III - ±500V
Latch-up JESD78, Trigger Class-II - ±200mA
In your opinion is this enough ? In the TPD4E02B04-Q1 data sheet they recommend on the USB 2.0 lines to use TPD4E05U06-Q1 ? What do you think ?
If we do use the TPD4E02B04-Q1 is there a reason why we couldn't use the TPD4E02B04-Q1 for the USB 2.0 lines \ CC lines instead of the TPD4E05U06-Q1 ?
