AMIS-42675
High Speed Low Power CAN
Transceiver for Long Wire
Networks
Description
The AMIS−42675 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 common−mode voltage range of the receiver inputs,
the AMIS−42675 is able to reach outstanding levels of
electro−magnetic susceptibility (EMS). Similarly, extremely low
electromagnetic emission (EME) is achieved by the excellent
matching of the output signals.
The AMIS−42675 is the industrial version of the AMIS−42665 and
primarily 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−42675 allows low transmit data rates down 10
Kbit/s or lower.
The AMIS−42675 is the low power member of the CAN high−speed
transceiver family and offers the following additional features:
