Latest Patents

One of Hayakawa's latest patents involves a clock data recovery circuit capable of generating a clock signal synchronized with a data signal. This innovative circuit utilizes a phase comparison circuit to detect the phase difference between a data signal and the output from a variable delay circuit. A Code Operator is employed to detect a value of a control code corresponding to a delay equal to one period of the output clock. When the delay amount of the variable delay circuit exceeds one period of a clock during synchronization, the control code is adjusted based on the detection results from the phase delay circuit. This allows for effective synchronization of the data signal and the clock, even in cases where there is a frequency difference.
