CAN Transceivers

The CAN transceiver has two tasks:

• Receiving: it adapts signal levels from the bus, to levels that the CAN Controller expects and has protective circuitry that protect the CAN Controller
• Sending: it converts the transmit-bit signal received from the CAN Controller into a signal that is sent onto the bus

The following is a list of known manufacturers of CAN transceivers.
Not all of there products are listed but sometimes products worth mentioning. Always check the manufacturers product pages.

Manufacturers working on CAN FD capable transceivers are marked with a CAN FD smily The main issue of CAN FD capable transceivers is the symmetry of the rising and the falling edges, which are required above 1 Mbit/s. CAN FD enhances the exchange of data up to 5 Mbit/s by using high-speed (HS) CAN transceivers. But its achievable data rate is not likely to exceed 2 Mbit/s in real topologies because of the effects of signal ringing. CAN SIC transceivers actively improve the signal and thus are less limited by ringing, achieving higher bit rates in more complex topologies.
