| 发明名称 | On-chip eye diagram capture | ||
| 摘要 | An eye diagram capture device includes a delay line arranged to receive a digital signal and output time delayed version of the digital signal. An edge detection circuit is arranged to receive the digital signal and the time delayed version of the digital signal, the edge detection circuit operating to output a signal corresponding to a logical value of the digital signal received coincident with an edge of the time delay version of the digital signal. A voltage comparator is arranged to receive the digital signal and a reference voltage. The voltage comparator operates to output a first signal when the a voltage of the digital signal and the reference voltage are equal to each other. | ||

| 主权项 | 1. An eye diagram capture device, which comprises: a delay line arranged to receive a digital signal and output a time delayed version of the digital signal; an edge detection circuit arranged to receive the digital signal and the time delayed version of the digital signal, the edge detection circuit operating to output a signal corresponding to a voltage of the digital signal received, which is stable before a leading edge of the time delayed version of the digital signal; and, a voltage comparator arranged to receive the digital signal and a reference voltage, the voltage comparator operating to output a first signal when the voltage of the digital signal and the reference voltage are equal to each other. | ||
