first embodiment
[0038]Please refer to FIGS. 2A-2C, which show the present invention. FIG. 2A shows a schematic diagram of an output stage circuit 21 configured to operably transmit data via a bus. As shown in FIG. 2A, the output stage circuit 21 comprises a controller 211 and a transceiver circuit 213. The controller 211 controls the transceiver circuit 213, to transmit or receive data via the bus (referring to the above-mentioned bus 12). The bus has a high side signal line, a low side signal line and an impedance circuit coupled between the high side signal line and the low side signal line. For example, as shown in FIG. 1A, the impedance circuit can include, for example but not limited to, two resistors RL. Each resistor RL has its two ends electrically connected to the high side signal line and the low side signal line, respectively. The high side signal line has plural high side output terminals CANH, which are respectively coupled to the corresponding data transceiver controller circuits 21. ...
second embodiment
[0050]Please refer to FIGS. 3A-3G, which show the present invention. FIG. 3A shows a schematic diagram of an output stage circuit 31 configured to operably transmit data via a bus. As shown in FIG. 3A, the output stage circuit 31 comprises a controller 311 and a transceiver circuit 313. The controller 311 can control the transceiver circuit 313, such that the output stage circuit 31 can transmit or receive data via the bus (referring to the above-mentioned bus 12). The bus has a high side signal line, a low side signal line and an impedance circuit coupled between the high side signal line and the low side signal line. For example, as shown in FIG. 1A, the impedance circuit can include, for example but not limited to, two resistors RL. Each resistor RL has its two ends electrically connected to the high side signal line and the low side signal line, respectively. The high side signal line has plural high side output terminals CANH, which are respectively coupled to the corresponding...
third embodiment
[0066]Please refer to FIG. 4, which shows the present invention. FIG. 4 shows a schematic diagram of an output stage circuit 41 configured to operably transmit data via a bus. As shown in FIG. 4, the output stage circuit 41 comprises a controller 411 and a transceiver circuit 413. The controller 411 can control the transceiver circuit 413, such that the output stage circuit 41 can transmit or receive data via the bus (referring to the above-mentioned bus 12). On one hand, each data transceiver controller circuit 41 can generate a differential output signal between the corresponding high side output terminal CANH and the corresponding low side output terminal CANL, so as to transmit data. On the other hand, each data transceiver controller circuit 41 can receive a differential input signal via the corresponding high side output terminal CANH and the corresponding low side output terminal CANL, so as to receive data.
[0067]Please still refer to FIG. 4. In the data transceiver controlle...
