AMIS-42671

AMIS-42671 High-Speed CAN Transceiver For Long Networks Data Sheet 1.0 General Description The AMIS-42671 CAN transceiver with autobaud is the interface between a controller area network (CAN) protocol controller and the physical bus. It may be used in both 12V and 24V systems. The transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller. Due to the wide common-mode voltage range of the receiver inputs, the AMIS42671 is able to reach outstanding levels of electromagnetic susceptibility (EMS). Similarly, extremely low electromagnetic emission (EME) is achieved by the excellent matching of the output signals. The AMIS-42671 is primarily intended for industrial network applications where long network lengths are mandatory. Examples are elevators, in-building networks, process control and trains. To cope with the long bus delay the communication speed needs to be low. AMIS-42671 allows low transmit data rates down 10 Kbit/s or lower. The autobaud function allows the CAN controller to determine the incoming baud rate without influencing the CAN communication on the bus. 2.0 Key Features Fully compatible with the ISO 11898-2 standard Autobaud function Wide range of bus communication speed (0 up to 1 Mbit/s) Allows low transmit data rate in networks exceeding 1 km Ideally suited for 12V and 24V industrial and automotive applications Low electromagnetic emission (EME) common-mode choke is...
