Overview
The TCAN1463-Q1 is a high-speed Controller Area Network (CAN) transceiver designed for automotive applications. It is AEC-Q100 qualified and meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification and the CiA 601-4 Signal Improvement Capability (SIC) specification. This device supports both classical CAN and CAN FD (flexible data rate) data rates up to 8 Mbps, enhancing signal quality and reducing ringing at the dominant-to-recessive edge. It is particularly useful in complex network topologies, enabling higher throughput and reliability.
