SIT1042AQ is an interface chip used between the CAN protocol controller and the physical bus. It can be used for in-vehicle, industrial control and other fields. It supports 5Mbps (CAN FD), and has the ability to perform differential signal transmission between bus and the CAN protocol controller. The SIT1042AQ is an upgraded version of the SIT1042Q with improved bus signal symmetry and lower electromagnetic radiation performance. In addition, the SIT1042AQ is fully compatible with SIT1042Q.
