摘要： In a data decision circuit: a clock generation unit generates a clock signal based on a phase difference signal so that the clock signal has an optimum phase with respect to a phase of an input data signal; a data determination unit determines data values carried by the input data signal, by using the clock signal; a phase-difference detection unit detects a rising-side phase difference and a falling-side phase difference, where the rising-side phase difference is a phase difference between a rising of the input data signal and a next transition in the clock signal, and the falling-side phase difference is a phase difference between the transition and a next falling of the input data signal; and a phase-difference-signal generation unit generates the phase difference signal so as to represent a difference between the rising-side phase difference and the falling-side phase difference.

摘要： Using a switching signal from a coarse/fine switching and operation mode switching circuit, the width of change of a counter control value during power up is increased, and the width of change is reduced once a steady state is reached. In the steady state, the frequency of updating is limited by a control signal from an update permit control circuit. In the steady state, the frequency band of a current source in an LD driving circuit is reduced in width.

摘要： A receiving/processing unit receives signals parallelized by a parallelizing unit, and executes a frame process including frame synchronization process on the signals. A phase comparing circuit and a phase judging circuit judge whether a bit delay is present based on a phase difference between a phase of a clock signal at a clock/data recovering unit and a phase of a clock signal at the parallelizing unit. The receiving/processing unit includes a logic processing circuit that executes a bit delay process based on a result of judgment by the phase comparing circuit and the phase judging circuit.

摘要： A coil package which makes it easy to handle a high-frequency cone/pyramid-shaped coil and enhance frequency characteristics without degrading the characteristics of the coil. The cone/pyramid-shaped coil has a conical or pyramidal shape formed by wiring a conductor wire around an outer peripheral surface of a core such that the winding diameter of the coil progressively decreases from one end to the other end of the coil. The coil and a dielectric substrate are integrated with each other by forming a hole for inserting a tip portion of the coil in the dielectric substrate, making the bottom of the hole and a back surface of the dielectric substrate electrically continuous by a via, placing the coil in the hole by directing a small-diameter side of the cone/pyramid-shaped coil to the hole, electrically connecting the bottom of the hole and a tip-side lead wire extending from the coil to each other, and connecting an electrode on a large-diameter side of the coil to an electrode on the dielectric substrate.
