AMIS-42671 High-Speed CAN Transceiver

For Long Networks

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 AMIS-

42671 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 no longer required

• Differential receiver with wide common-mode range (+/- 35V) for high EMS

• No disturbance of the bus lines with an un-powered node

• Thermal protection

• Bus pins protected against transients

• Silent mode in which the transmitter is disabled

• Short circuit proof to supply voltage and ground

• Logic level inputs compatible with 3.3V devices

• ESD protection for CAN bus at ± 8 kV
