CAN Transceivers Operate Over 500m for Industrial Networks

Due to thewide common-mode voltage range of its receiver inputs, the AMIS-42671 CAN transceiver displays extremely low electromagnetic susceptibility (EMS).

Similarly, very low electromagnetic emission (EME) is achieved by the excellent matching of the output signals.

The transceiver provides differential-transmit capability to the bus and differential-receive capability to the CAN controller. As a result the AMIS-42671 supports industrial network applications requiring long cable runs. The AMIS-42671 CAN transceiver with autobaud function implements the interface between a Controller Area Network (CAN) protocol controller and the physical bus. To cope with the long bus delay the communication speed needs to be low. AMIS-42671 allows low transmitted data rates down to 10kbit/s or lower. The autobaud function allows the CAN controller to determine the incoming baud rate without influencing the CAN communication on the bus. These transceivers may be used in both 12V and 24V systems.

ON Semiconductor also offer a range of other transceivers supporting long network requirements.

These include the AMIS-42673 high-speed 3.3V digital-interface CAN transceiver, the AMIS-42675 high-speed low-power CAN transceiver, and the AMIS-42770 dual high-speed CAN transceiver.
