摘要： A digital PLL circuit employs a fixed-frequency output signal from a fixed-frequency oscillator, to provide a signal synchronized with an external reference signal. The digital PLL circuit has a counter and an adjuster. The counter counts clock periods (clock pulses) of the fixed-frequency output signal. The adjuster increments or decrements a value counted by the counter a predetermined number of times in a predetermined period according to a deviation of the fixed-frequency output signal from the reference signal. This digital PLL circuit is inexpensive because it employs no DA converter nor VCO.

摘要： In an information reproducing apparatus having an open architecture, a secure module stores first information, and has a structure which does not allow access to the first information from outside, and a memory has a structure which can be accessed from outside. A decryption unit loaded in the memory decrypts an encryption applied to the first information by using a predetermined key. A key supply unit implemented in the secure module supplies the predetermined key to the decryption unit. An authentication unit implemented in the secure module supplies second information to the decryption unit, refers to third information returned in response to the second information, and checks for authenticity of the decryption unit. A key-supply stop unit implemented in the secure module stops supply of the predetermined key by the key supply unit when the authentication unit does not authenticate the decryption unit.

摘要： A method tests connections between terminal of a first semiconductor integrated circuit and terminals of a second semiconductor integrated circuit. These first and second semiconductor integrated circuits are mounted on a printed circuit board. The first semiconductor integrated circuit has a test data generator for generating test data for the terminal connection test, a selector for selecting outputs of the test data generator during the terminal connection test, and a test data output unit for providing the test data from the selector to the outside. The second semiconductor integrated circuit has a test data fetch-hold unit for fetching and holding the test data provided by the first semiconductor integrated circuit. This method is characterized by verifying whether or not an output of the test data fetch-hold unit represents a predetermined value, to thereby test the terminal connections of the first and second semiconductor integrated circuits and the AC characteristics thereof.
