3.3

USB Interface

PVS8 supports a USB 2.0 High Speed (480Mbit/s) device interface that is Full Speed (12Mbit/s) 
compliant. The USB interface is primarily intended for use as command and data interface and 
for downloading firmware. 

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 PVS8 is designed as a self-powered device compliant with the “Universal Serial Bus 
Specification Revision 2.0”

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.

 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 90Ohm for proper signal integrity.
