Figure 9. Transmitter Characteristics (BGE

→ BUS, while TxEN is low)

The transmitter generates the FlexRay differential bus voltage according to input signal on TxD as shown in Figure 10.

→ BUS

In NORMAL and RECEIVE-ONLY mode the transmitter drives Idle on the bus in case no data are transmitted. In STANDBY, GO-TO-SLEEP and

SLEEP mode the transmitter drives Idle_LP (idle low-power) on the bus pins. In POWER_OFF mode the bus pins shows Idle_HZ (idle high

impedance).
