9.1.1 Signal Improvement
The TCAN1463-Q1 includes the Signal Improvement Capability (SIC) that enhances the maximum data rate achievable in complex star topologies by minimizing signal ringing. Signal ringing is the result of reflections caused by impedance mismatch at various points in a complex CAN network.
An example of a star network is shown Figure 9-1.
Figure 9-1 CAN network: Star TopologyRecessive-to-dominant signal edge is usually clean as it’s strongly driven by the transmitter. Transmitter output impedance of CAN transceiver is RID(dom) and matches to the network characteristic impedance. For a regular CAN FD transceiver, dominant-to-recessive edge is when the driver output impedance goes to ~60 kΩ and signal reflected back experiences impedance mismatch which causes ringing. The TCAN1463-Q1 resolves this issue by TX-based Signal improvement capability (SIC). The TCAN1463-Q1 continues to drive the bus recessive strongly till tSIC_TX_base to minimize the reflections and the recessive bit is clean at the sampling point. In the active recessive phase, transmitter output impedance is low (RID(active_rec)). After this phase, the device enters into a passive recessive phase where the driver goes into high impedance state. This phenomenon is explained using Figure 9-2. For further information, please refer to the white paper on how SIC unlocks the real potential of CAN-FD transceivers.
