2.1.3 USB Interface
TX62/TX82 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed
(12Mbit/s) compliant.
The external application is responsible for supplying the VUSB_IN line. This line is used for ca-
ble detection only. The USB part (driver and transceiver) is supplied by means of BATT+. This
is because TX62/TX82 is designed as a self-powered device compliant with the “Universal Se-
rial Bus Specification Revision 2.0”

.
Figure 9: USB circuit
To properly connect the module's USB interface to the external application, a USB 2.0 compat-
ible connector and cable or hardware design is required. For more information on the USB re-
lated signals see Table 4. Furthermore, the USB modem driver distributed with TX62/TX82
needs to be installed.

If the USB interface is operated in High Speed mode (480MHz), it is recommended to take
special care routing the data lines USB_DP and USB_DN. Application layout should in this
case implement a differential impedance of 90 ohms for proper signal integrity.
