AMIS-42671

High Speed Autobaud CAN

Transceiver

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 12 V and 24 V 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.
