摘要： In some embodiments, the inventions includes a transmitter including a cycle encoding circuit to receive a data input signal and to provide a full cycle encoded signal in response thereto by continuously joining portions of different encoding signals. Some of the encoding signals have a different frequency than others of the encoding signals and some of the encoding signals have a different phase than others of the encoding signals. Data is represented in data time segments of the full cycle encoded signal and no data time segment has more than one cycle of an encoding signal. In some embodiments, a receiver receives the cycle encoded signal and recovers data of the data input signal. Still other embodiments are described and claimed.

摘要： According to some embodiments, an interpolated clock signal having a first frequency is received, and the interpolated clock signal is periodically sampled based on a reference clock signal to generate periodically-sampled values, the reference clock signal having substantially the first frequency. A phase of the interpolated clock signal may be set to a phase degree at which the periodically-sampled values resolve to more than one value, and the phase of the interpolated clock signal may be incrementally changed until the periodically-sampled values resolve to one value. A non-linearity of the interpolated clock signal may be determined based on the number of incremental changes.
