PROBLEM TO BE SOLVED: To provide a binary value conversion circuit capable of high speed operation with a concise circuitry.SOLUTION: A binary value conversion circuit 18 has a phase detection circuit 14 receiving a plurality of clock signals having the same period and the edges of different phases, and a transition signal transiting from a first level to a second level, and outputting a first binary value indicating the context of the transition timing of a transition signal from the first level to the second level, and outputting a first binary value indicating the context of transition timing of a transition signal from the first level to the second level, and an encoder 15 having binary value storage circuits 53-55 for storing a plurality of binary values, and selection circuits 511-518, 521-528 for selecting any one of the plurality of binary values based on the first binary value. A second binary value where the inverted bit obtained by inverting the least significant bit of the first binary value is the most significant bit, and any one of the plurality of binary values selected based on the first binary value is the least significant bit from one bit lower than the most significant bit is outputted.SELECTED DRAWING: Figure 12 |
