describe

SIT1051A is an interface chip used between CAN protocol controllers and physical buses, which can be applied in fields such as trucks, buses, cars, industrial control, etc. It supports 5Mbps flexible data rate CAN FD and has the ability to transmit differential signals between buses and CAN protocol controllers.

SIT1051A is an upgraded version of the SIT1051 chip, which improves the symmetry of the bus signal and has lower electromagnetic radiation performance. Additionally, SIT1051A is fully compatible with SIT1051.
