tBUS Dominant time required on bus for wakeup from standby STB at VCC, See Figure 13 1 5 µs
The TXD dominant time-out (t(dom)) disables the driver of the transceiver once the TXD has been dominant longer than t(dom), 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 5 successive dominant bits are followed immediately by an error frame. This, along with the t(dom) minimum, limits the minimum bit rate. The minimum bit rate may be calculated by:
Minimum Bit Rate = 11/ t(dom) = 11 bits / 300 µs = 37 kbps
