ABSTRACT:
An edge integrating phase detector for a phase locked loop passes a portion of a sync edge of an input video signal as a sampled signal to an integrator in response to a gate pulse nominally centered on a timing reference point of the sync edge. The sampled signal has a positive and negative portion. The integrator produces from the sampled signal a control signal for a VCO that is proportional to the unbalance between the positive and negative portions. The gate pulse is generated from the output of the VCO as a function of the nominal period of the input video signal.
