titleOfInvention | Phase synchronizing device and method, and optical disk device |
abstract | Provided is a phase synchronizing device having a quickly drawable PLL circuit. When this PLL circuit (17) comes into an asynchronous state, a maximum code inversion interval meter (18) measures the maximum of a code inversion interval in discrimination data outputted by a PRML block (16). A first channel frequency estimator (19) estimates a channel frequency, on the basis of the maximum of the code inversion interval, and outputs an estimated channel frequency fdet_T. The PLL circuit (17) sets the center frequency to the estimated channel frequency fdet_T. After this, a sync interval meter (20) measures a sync interval from the discrimination data. A second channel frequency estimator (21) estimates the channel frequency on the basis of the sync interval measured, and outputs an estimated channel frequency fdet_S, and the PLL circuit (17) sets the center frequency to the estimated channel frequency fdet_S. |
