1 _{These are average IDDE for worst case PVT from simulation. Currents apply to output pins only for the fast pads and to input}
pins only for the medium pads.
2 _{All loads are lumped.}
5.7.3 LVDS pad specifications
LVDS pads are implemented to support the MSC (Microsecond Channel) protocol, which is an enhanced feature of the DSPI
module.
