Abstract
A method and apparatus are provided for recovering multiphase modulated data. A signal pulse of a fixed duration is generated upon the transition of a first phase component of a multiphase modulated signal transmitted at a fixed bit rate. A data clock signal having a frequency in synchronism with the bit rate is generated in response to an error signal. The data clock signal is delayed by a delay of approximately one half the duration of the signal pulse. The delayed clock is gated using the signal pulse to provide the error signal that establishes the data clock frequency. Components of the multiphase signal are sampled using the phase locked data clock to recover data.
