COMMUNICATION INTERFACE CHARACTERISTICS (Cont’d)
13.11.4 USB - Universal Bus Interface
Note 1: RL is the load connected on the USB drivers.
Note 2: All the voltages are measured from the local ground potential.
Note 3: An external decoupling capacitor (typical 100nF, min 47nF) must be connected between this pin
and USBV
Figure 92. USB: Data Signal Rise and Fall Time
Note1: Measured from 10% to 90% of the data signal. For more detailed informations, please refer to
Chapter 7 (Electrical) of the USB specification (version 1.1).
