A bursty phase detector comprises upper and lower branches. The upper branch includes a voltage-controlled oscillator (VCO) providing a VCO phase; a phase detector with a first input for receiving a data stream and a second input coupled to the output of the VCO, the phase detector providing a phase error; a sample selector with a first input for receiving a sum of the VCO phase and the phase error, and a second input coupled to receive the data stream, the sample selector providing a data stream sample; a signal stream detector with a first input for receiving the sum of the VCO phase and the phase error, and a second input coupled to the output of the sample selector, the signal stream detector generating a data stream phase and a data stream detect signal. The lower branch includes a delay component with an input for receiving the data stream. |
