AMIS-42675
High Speed Low Power CAN
Transceiver for Long Wire
Networks
Description
The AMIS42675 CAN transceiver 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 commonmode voltage range of the receiver inputs,
the AMIS42675 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 AMIS42675 is the industrial version of the AMIS42665 and
primarily for applications where long network lengths are mandatory.
Examples are elevators, inbuilding networks, process control and
trains. To cope with the long bus delay the communication speed
needs to be low. AMIS42675 allows low transmit data rates down 10
Kbit/s or lower.
The AMIS42675 is the low power member of the CAN highspeed
transceiver family and offers the following additional features:
