    • A synchronous clock generation apparatus including a multiplier for multiplying a horizontal synchronizing signal by a horizontal synchronizing pulse signal to generate multiplication data, a gain variable digital LPF for extracting only DC components from the multiplication data and capable of performing gain adjustment, and a controller for calculating gain adjustment data, lock center frequency setting data, and LPF gain adjustment data based on the correction data. The controller detects an amount of deviation from the lock center frequency and an amount of variation, displaces the lock center frequency and shifts the lock range along the frequency axis to enlarge the apparent lock range when the amount of deviation is large, and reduces the gain to improve lock precision when the amount of variation is small, without expanding bits in the circuit configuration.

    • A data slicer 300 includes a slice level calculation unit 310 that determines whether a detected digital video signal is a CRI signal on the basis of the amplitude of the signal, and sets a reference slice level and upper and lower slice levels which are obtained by providing offset in the reference slice level, by using only the CRI signal; a data slicing unit 160 that binarizes a digital video signal S140 using the slice levels; a decoding circuit 170 that converts binarized serial data into parallel data; and a data selection unit 320 that selects data including no error from the decoded data, and outputs the selected data through a video signal output terminal 190. Therefore, even when the video signal is distorted, this data slicer can set appropriate slice level data to binarize the video signal, thereby suppressing the occurrence rate of decoding errors.
