15.1.4 Wake-up signaling via RXD pin
Work around
To keep the differential bus amplitude in the entire system above 600 mV, the cable
impedance of the chosen bus cable shall be higher than 110 . Moreover, the termination
resistance at the two bus ends shall be not lower than 110 .
In case of an undervoltage condition at V
Consequence
In case of an undervoltage condition at V
the TJA1080 can give a continuous signaling of a wake-up event on pin RXD. This
behavior is not conform to the FlexRay Electrical Physical Layer specification (see
Work around
Use the RXEN pin for wake-up recognition when the V
is available.
