Note:
6. PCIe interface #2 can be brought to the PEX1 pins, or USB 3.0 port #1 to the USB_SS0 pins on Jetson TX2/TX2i depending
on the setting of a multiplexor on the module. The selection is controlled by QSPI_IO2 configured as a GPIO.
7. Jetson TX2/TX2i has been designed to enable use cases listed in the table above. However, released Software may not
support all configurations, nor has every configuration been validated.
o Configuration #1 & 2 represent the supported and validated Jetson TX2/TX2i Developer Kit configurations. These
configurations are supported by the released Software, and the PCIe, USB 3.0, and SATA interfaces have been
verified on the carrier board.
8. See notes under the Backward Compatible mapping table related to color coding, PCIe x2/x1 support & lane reversal.

Note:
1. Common mode filters on USB[2:0]_DP/DN (USB 2.0 interfaces) are optional. Place only as needed if EMI is an issue.
Common mode filters on USB3_TX/RX_P/N signals are not recommended. If common mode devices are placed, they
must be selected to minimize the impact to signal quality, which must meet the USB spec. signal requirements. See the
Common Mode Choke requirements in the USB 3.0 Interface Signal Routing Requirements table .
2. If USB 3.0 is routed to a connector, only AC caps on the module TX lines are required. If routed directly to a peripheral,
AC caps are needed for both the module TX lines (connected to device RX) & Device TX lines (connected to the module
RX).
