http://quarch.com/news/automotive-physical-layer-testing/ WebAt the physical layer, both SCL and SDA lines are of the open-drain design, thus pull-up resistors are needed. High-speed systems (and some others) may use a current source instead of a resistor to pull up only SCL or both SCL and SDA, to accommodate higher bus capacitance and enable faster rise times.
