- PHASE DETECTOR FOR REALIZING OUTPUTS HAVING THE SAME WIDTH OF PULSE AND CLOCK AND DATA RECOVERY CIRCUIT USING THE SAME

摘要

A phase detector for making the pulse width of the phase data equal to the pulse width of the restored clock and a clock-data restoring circuit using the same. The phase detector outputs a phase shift data indicating a phase error of the input data and a restored clock using a clock and an output of the data timing shift detection unit to detect a transition of bit timing of input data And a phase error detecting unit. Here, the pulse width of the phase data is equal to the pulse width of the restored clock.
