Abstract
Techniques including methods and apparatus for calibrating a local clock are provided in an implantable medical device. The implantable medical device includes a telemetry module for receiving a remote signal transmitted by an external device. The received signal is provided to a clocking circuit having a clocking circuit for computation of a calibration factor based on a difference between phases of the clock signal generated by the local clock and transitions in the received remote signal. The calibration factor may be derived as a function of an edge of the clock signal lagging or leading relative to a corresponding edge of the remote signal.
