Title:
PHASE LOCKED LOOP CIRCUIT
Document Type and Number:
Japanese Patent JPH09326691
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a phase locked loop circuit for not generating malfunction of the entire circuit with simple constitution. SOLUTION: This phase locked loop circuit for following up the phase of input signals is provided with a phase comparator 150 for performing phase comparison of inputted reference signals and the input signals inputted as a comparison object synchronized with prescribed operation clocks. Thus, since a first detection part 154, a second detection part 155 and JK flip-flops 162 and 163 perform the output operation of data corresponding to the prescribed operation clocks, phase deviation between NU data and ND data generated based on the difference of the delay amounts of respective input data by a part taking loop or feedback constitution and the phase deviation between two tri-state logic outputs are not generated.
