Abstract
A transceiver configured to send and receive data over a data bus is disclosed. The transceiver includes a communication port to connect to the data bus, a bus idle detector configured to detect when the data bus is idle, a TXDC interface configured to selectively receive and send data and an RXDC interface configured to send data. The transceiver also includes a switch controlled by an output of the bus idle detector. The switch is configured to cause the TXDC interface to be used for sending data out when the bus idle detector detects that the data bus is idle.

A transceiver configured to send and receive data over a data bus, the transceiver comprising:
- a communication port to connect to the data bus;
- a bus idle detector configured to detect when the data bus is idle;
- a TXDC interface configured to selectively receive and send data;
- an RXDC interface configured to send data;
- and
- a switch controlled by an output of the bus idle detector, wherein the switch is configured to cause the TXDC interface to be used for sending a data out when the bus idle detector detects that the data bus is idle.
