Hi,
On the MC13192 page I found "1319xSARD Reference Design that complies to RoHS" rev3.03 named 1319xSARD.zip. It includes the PCB layout and schematic of DIG536-3, but I have the DIG536-2.
Although they may look the same, there are differences in powersuply, powerswitch, antenna-decoupling.
Where can I find older versions of 1319xSARD.zip?
