Times are specified with loads of 1.35 k pull-up resistance and 57 pF load capacitance on port B, and 167
57 pF load capacitance on port A. Different load resistance and capacitance will alter the RC time constant, thereby changing the
propagation delay and transition times.
Pull-up voltages are V

The proportional delay data from port A to port B is measured at 0.3V
The enable pin, EN, should only change state when the global bus and the repeater port are in an idle state.

IL
specification is for the first LOW level seen by the SDAB/SCLB lines. V
for port A with envelope noise must be below 0.3V
