AMIS-42670
High-Speed CAN
Transceiver for Long
Networks
Description
The AMIS−42670 CAN transceiver is the interface between a
controller area network (CAN) protocol controller and the physical
bus and 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−42670
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−42670 is the industrial version of the AMIS−30660 and
primarily intended for 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−42670 allows low transmit data rates
down 10 kbit/s or lower.
