Coarse frequency detector system and method thereof

An improved coarse frequency detector includes a first storage device responsive to a data signal and a sub-multiple of a clock signal for detecting a first transition in the data signal during a predetermined state of the sub-multiple of the clock signal and generating an intermediate signal, and a...

More Information
Summary:An improved coarse frequency detector includes a first storage device responsive to a data signal and a sub-multiple of a clock signal for detecting a first transition in the data signal during a predetermined state of the sub-multiple of the clock signal and generating an intermediate signal, and a second storage device responsive to the data signal and the intermediate signal for detecting a second transition in the data signal having the same polarity as the first transition during the predetermined state of the sub-multiple of the clock signal and generating an up-pulse.
