1. An implantable medical device, comprising:
an implantable resonant circuit comprising an implantable coil;
an external resonant circuit comprising an external coil configured to transcutaneously transfer power and data to the implantable resonant circuit using separate power and data time slots, respectively; and
external radio-frequency (RF) interface circuitry configured to drive the external resonant circuit at a first frequency during the power time slots and to drive the external resonant circuit at a second frequency during the data time slots, wherein the second frequency is different from the first frequency.
