IPC: H04L7/033
Filed: 1981-10-19
Abstract: PURPOSE:To deal with an abrupt shift in phase by controlling the variable frequency dividing circuit of an internal reference signal generating means while giving warning once a variable delay means reaches a minimum or maximum set value, and thus varying a reference signal and returning the operation point of the variable delay means to the center. CONSTITUTION:A digital signal from an input terminal 1 is delayed through a variable delay circuit 6 by a value set in initialization, and then outputted to an output terminal 2. A synchronizing signal detecting circuit 13 detects a synchronizing signal to output pulses at equal intervals when no phase shift is found. The output of a quartz oscillator 3, on the other hand, is frequency-divided by a variable frequency divider 4, and a phase difference detecting circuit 8 detects the phase shift between the circuits 4 and 13 to control a variable delay circuit 5, thereby correcting their phase shift. This correction is performed at the set period of a timer circuit 7 and a phase monitoring circuit 10 monitors the phase difference; when a preset phase difference is detected, a phase difference detecting circuit 9 detects the phase difference in output between the circuit 5 and synchronous detecting circuit 12. Then, the circuits 4 and 6 are controlled through a control circuit 14 to deal with an abrupt phase shift.

Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To obtain a frequency synthesizer by which versatility is not lost, even in the case of integration with a circuit of a reception system by means of IC conversion and a circuit of the reception system is not disturbed. SOLUTION: A local signal with a frequency being several times as large as the number of frequency division in a frequency dividing part 100, based on a reference signal generated by a reference signal oscillator 1 by loop control consisting of a phase comparator 2, a low-pass filter 3, a voltage-controlled oscillator 4 and the frequency-dividing part 100. In the part 100, a pre-scaler 5 divides the frequency of the local signal by the frequency division number corresponding to a change-over signal from a polarity switch 27. The switch 27 is operated as a simple buffer, when a change-over control signal is at 'L' level and outputs the frequency division result of a variable frequency divider 70 to the pre-scaler 5 as is as the change-over signal.  In the meantime, when the change-over control signal is at 'H' level, it operates as an inverter, inverts the frequency division result of the divider 70, and outputs it to the pre-scaler 5 as the change-over signal.
