(1) The TXD dominant time out (tTXD_DTO) disables the driver of the transceiver once the TXD has been dominant longer than tTXD_DTO, which releases the bus lines to recessive, preventing a local failure from locking the bus dominant. The driver may only transmit dominant again after TXD has been returned HIGH (recessive). While this protects the bus from local faults, locking the bus dominant, it limits the minimum data rate possible. The CAN protocol allows a maximum of eleven successive dominant bits (on TXD) for the worst case, where five successive dominant bits are followed immediately by an error frame. This, along with the tTXD_DTO minimum, limits the minimum bit rate. The minimum bit rate may be calculated by: Minimum Bit Rate = 11/ tTXD_DTO = 11 bits / 1.2 ms = 9.2kbps.
(2) The RXD timeout (tRXD_DTO) disables the RXD output in the case that the bus has been dominant longer than tRXD_DTO, which releases RXD pin to the recessive state (high), thus preventing a dominant bus failure from permanently keeping the RXD pin low. The RXD pin will automatically resume normal operation once the bus has been returned to a recessive state. While this protects the protocol controller from a permanent dominant state, it limits the minimum data rate possible. The CAN protocol allows a maximum of eleven successive dominant bits (on RXD) for the worst case, where five successive dominant bits are followed immediately by an error frame. This, along with the tRXD_DTO minimum, limits the minimum bit rate. The minimum bit rate may be calculated by: Minimum Bit Rate = 11 / tRXD_DTO = 11 bits / 1.6ms = 6.9kbps.
