Patent ID: 8666010

Claim:
A bursty phase detector for processing a data stream, comprising: an upper branch, including: a voltage-controlled oscillator (VCO) configured to provide a VCO phase at an output of the VCO; a phase detector with a first input coupled to receive the data stream and a second input coupled to the output of the VCO, the phase detector configured to provide a phase error at its output; a sample selector with a first input coupled to receive a sum of the VCO phase and the phase error, and a second input coupled to receive the data stream, the sample selector configured to provide a data stream sample at its output; and a data stream detector with a first input coupled to receive the sum of the VCO phase and the phase error, and a second input coupled to the output of the sample selector, the data stream detector configured to generate a data stream phase and a data stream detect signal; and a lower branch, including a delay component with an input coupled to receive the data stream.
