Modulation on the reader antenna is limited towards
maximum modulation depth, to prevent the reader from
going into power down.
Modudepth = (VPPmax-VPPmin)/( VPPmax+VPPmin)
Since Vppmin (Vmodu=4.2V)=1.6V,
and Vppmax (Vmodu=0.8V)=8.4, modudepthmax=68%.

The data slicer samples every 4 clock periods(=1/Fres),
therefore any pulse on the output can be 4 periods off.
