Figure 25: phyCORE-iMX Carrier Board USB-Host Interface
The i.MX35x controller comes with an integrated USB-Host-Phy, so that there is nothing more needed
than an USB connector.
So the USB Host Transceiver (U26) that is realized on the i.MX Carrier Board is not needed with the
phyCORE-i.MX35 module. There is a possibility to bypass the USB Host Transceiver (U24) via the
jumpers JP42 to JP46 on the i.MX Carrier Board.
For further details and jumper settings have a look at Table 30.
