Abstract
Embodiments of a method and a device are disclosed. In an embodiment, a method for operating a Controller Area Network (CAN) transceiver involves detecting phase information related to a CAN data frame that is transmitted by the CAN transceiver and in response to the phase information, switching between different transmitter configurations of the CAN transceiver within a bit interval for use in transmitting subsequent bits of the CAN data frame.

A method for operating a Controller Area Network (CAN) transceiver, the method comprising:
- detecting phase information related to a CAN data frame that is transmitted by the CAN transceiver;
- and
- in response to the phase information, switching between different transmitter configurations of the CAN transceiver within a bit interval for use in transmitting subsequent bits of the CAN data frame.
A Controller Area Network (CAN) transceiver, the CAN transceiver comprising:
- a transmitter unit configured to transmit a CAN data frame;
- and
- a protocol sampler connected to the transmitter unit and configured to:
- detect phase information related to the CAN data frame;
- and
- in response to the phase information, switch between different transmitter configurations of the transmitter unit within a bit interval for use in transmitting subsequent bits of the CAN data frame.
A method for operating a Controller Area Network (CAN) transceiver, the method comprising:
- detecting phase information related to a CAN data frame that is transmitted by the CAN transceiver, wherein the phase information indicates a data phase that follows an arbitration phase, and wherein the CAN transceiver has exclusive access to a CAN bus during the data phase;
- and
- in response to the phase information, switching from a first transmitter of the CAN transceiver to a second transmitter of the CAN transceiver within a bit interval for use in transmitting subsequent bits of the CAN data frame, wherein the second transmitter has a higher transmission data rate than the first transmitter.
