Method and apparatus for clock recovery and data retiming for random NRZ data

摘要: A method and apparatus for recovering a clock signal from random NRZ data is shown to include phase detector (22) detecting the difference between generating representative of difference. The binary having first second logic levels, wherein level an early relationship with late signal. Clock recovery also incorporates integrator (24) integrating over period time integration such oscillator (26) at frequency responsive both determined by centering factor offset factor. controlled There particular (36,38,40,42,44), several integrators preferred (28,30,32,34) practicing invention.
