Abstract: PURPOSE:To obtain stable oscillation at the wide range of frequencies and to prevent the occurrence of discontinuation of oscillation, by constituting an oscillator circuit constituting the PLL loop of a crystal oscillator circuit and stabilizing original oscillation by performing it with the crystal oscillator circuit, and then, resetting the original oscillation so that it can synchronize with a synchronizing signal inputted from the outside. CONSTITUTION:An original oscillator 1 composed of a crystal oscillator circuit socillates at, for example, 14MHz and the oscillation output is divided by a counter 2 which works at a driver. Phases of the divided output and an externally inputted synchronizing signal are compared with each other with a flip flop (FF) 5. When the oscillator 1 is set at, for example, 14,31818MHz for oscillation, the divider can divide a frequency into 1/4096 with its 12-bit counter 2 and the divided result of the 14.31818MHz becomes appox. 3495.6Hz. In the case of 1/4095, the divided result becomes 3496.5Hz and a step of about 1.0Hz can be obtained. Moreover, in the case of 1/320 and 1/319, the results become 44.744kHz and 44.885kHz, respectively, and a step of about 140Hz is obtained. If this circuit is used to cover the range of 15-45kHz, the difference of not more than 150Hz can be obtained against external inputted synchronizing signals.
