Abstract
PURPOSE: To reduce the transient change state of a PLL loop to shorten the time for stability by switching the state to a high-output impedance state of contents of the shift register and a state where contents stored in the shift register are outputted.
CONSTITUTION: Capacitors 56 to 60 are inserted one by one between each of parallel output terminals of shift register 48, which has a series input terminal, parallel output terminals and a control input terminal and stores plural-bit data, and one common earth terminal. parallel output terminals of register 48 are connected to parallel preset input terminals of variable frequency divider 40, which has plural parallel preset input terminals, respectively. During the data input period to register 48, two-state parallel output terminals do not output data and take a high-output impedance state; and during the data no input peiod, two-state parallel output terminals take a state where data stored in register 48 is outputted.
