    • PROBLEM TO BE SOLVED: To provide a system, an apparatus and a method for testing about a high-speed data transmission error. SOLUTION: The method, the apparatus and the system for testing an error in a high-speed input-output system are available. The system and the apparatus include a simultaneous code checker for testing the error in an encoded data packet through a static characteristic of a data packet and a dynamic characteristic of a data stream including a packet. The method sometimes takes a step to detect an invalid encoded packet by using the static characteristic of the data packet and the dynamic characteristic of the data stream including the packet. The method for optimizing a design of a simultaneous code checker logic uses an unspecified condition, and a simultaneous code checker circuit reduces a logic element and a semiconductor area requirement.

    • PROBLEM TO BE SOLVED: To provide a method for multiple-phase clock generation. SOLUTION: In one embodiment, a multiple-stage voltage controlled oscillator ("VCO") (302) transmits a plurality of clock phases (ck0-ck5) to a clock divider (304) which produces the desired number of clock phase outputs. The clock divider (304) in this embodiment includes a state machine, e.g., a modified Johnson counter (316), that provides a plurality of divided down clock phases, each of which is connected to separate modified shift registers (306-314). Each modified shift register contains D-type flip-flops and each D-type flip-flop provides a separate clock phase output. In one embodiment, the number of clock phase outputs of the multiple-phase clock is a function which multiplies the number of VCO clock phases by the number of desired states in the modified Johnson counter.

    • PROBLEM TO BE SOLVED: To provide a method and system for providing a clock signal with less power.SOLUTION: A method and system called a hybrid clock system is provided, which provides a clock signal with less power consumption. The hybrid clock system uses a PLL for high-speed data transfer but is provided with a power-saving mode for transferring data with less power consumption. In a normal mode, the hybrid clock system includes a reference clock running at a low frequency for driving the PLL. The PLL multiplies the reference clock frequency to a much higher frequency and supplies the frequency-multiplied reference clock to a transfer circuit. In the power saving mode, the hybrid clock system turns the PLL off and connects the reference clock directly to the data transfer circuit.
