An integrated circuit is described. This integrated circuit may include an input connector, coupled to a signal line, that conveys an input signal corresponding to encoded data, where the encoded data is encoded using a BMC, and the input signal may have different rise times and fall times. Moreover, the integrated circuit may include a recovery circuit, coupled to the input connector, that outputs the data based at least in part on a first threshold and a second threshold, where the output data may include data values with equal half-bit periods and variable frequency. Note that the recovery circuit may implement a state machine corresponding to the data.
