Abstract: Described embodiments provide a transmitter for transmitting data over a serial bus coupled to the transmitter. The transmitter includes a controller to generate data for transmission by the transmitter. A transmit driver is coupled to the controller. The transmit driver, in response to the generated data for transmission, generates logic transitions on the serial bus. The transmit driver generates low-to-high logic transitions on the serial bus by charging the serial bus by a bus current based on (i) a predetermined initial bias level for a first time period, and (ii) a first predetermined maximum bias level for a second time period. The transmit driver generates high-to-low logic transitions on the serial bus by discharging the serial bus by a bus current based on (i) a pre-charged level of the transmit driver, and (ii) a second predetermined maximum bias level for a third time period.
