| titleOfInvention | PLL control circuit of optical disc apparatus, program for controlling optical disc apparatus |
| abstract | A PLL control circuit for an optical disc apparatus that boosts an output voltage of a charge pump (CP) circuit based on an RF signal exceeding a predetermined level regardless of phase comparison between a binarized signal and a frequency signal, It is an object to provide a program for controlling an optical disk device. A voltage frequency conversion circuit for generating a first frequency signal based on a control voltage and a phase difference signal indicating a phase difference between the first frequency signal and a second frequency signal generated based on an RF signal are generated. A PLL control circuit including a phase comparison circuit and a CP circuit that generates a control voltage to synchronize the phase according to the phase difference signal, a first detection circuit that detects an RF signal exceeding a predetermined level, and phase synchronization A second detection circuit for detecting whether or not a predetermined level of the RF signal is detected, a control voltage is generated regardless of the phase difference signal, and when phase synchronization is detected, a control voltage is generated according to the phase difference signal. And a control circuit for controlling the CP circuit so as to be generated. [Selection] Figure 3 |
