I found an app note on the Lattice site about using the LVDS input as the input comparator. My design is very low power and I am concerned about the power consumption of this input. Typically inputs are not supposed to operate in the linear region as this draws extra power in a "shoot through" mode. The LVDS spends its entire time in this region.
Will this cause the power consumption to increase compared to a single ended input driven digitally?
The parts I'm considering are the iCE40 and iCE65 chips from Lattice, formerly Silicon Blue. The iCE65 is obsolete, but this is a proof of concept so I don't much care if I can't use it in production. It has better leakage current specs.
