Transmitter circuit and method for operating thereof

A method for operating a transmitter circuit,

• the transmitter circuit comprising:
• a first circuit configured to transmit data in a first data transmission mode, wherein in the first data transmission mode, a first transmission value is provided by a potential between a first conductor and a second conductor determined by a terminating resistor, and wherein a second transmission value is provided by applying a first reference potential to the first conductor and a second reference potential, which is different from the first reference potential, to the second conductor;
• a second circuit configured to transmit data in a second data transmission mode, wherein in the second data transmission mode, a first transmission value is provided by applying a third reference potential to the first conductor and a fourth reference potential to the second conductor, and a second transmission value is provided by applying the fourth reference potential to the first conductor and the third reference potential to the second conductor;
• and
• a switching circuit configured to control the first circuit and the second circuit to transmit data in the first data transmission mode or in the second data transmission mode;
• the method comprising:
• operating the transmitter circuit either in the first data transmission mode or in the second data transmission mode;
• and
• switching the operation mode of the transmitter circuit from the one data transmission mode to the other data transmission mode;
• wherein
• in the first data transmission mode, controlling the first circuit configured to transmit data includes providing the first transmission value by the potential between the first conductor and the second conductor determined by the terminating resistor, and providing the second transmission value by applying the first reference potential to the first conductor and the second reference potential, which is different from the first reference potential, to the second conductor;
• in the second data transmission mode, controlling the second circuit configured to transmit data includes providing the first transmission value by applying the third reference potential to the first conductor and the fourth reference potential to the second conductor, and providing the second transmission value by applying the fourth reference potential to the first conductor and the third reference potential to the second conductor.
