Abstract | A semiconductor device includes: a data sampler configured to receive a data signal having a first frequency and sample the data signal with a clock signal having a second frequency higher than the first frequency, and output data of a time corresponding to a unit interval of the data signal; an error sampler configured to sample the data signal with an error clock signal having a second frequency and having a phase different from that of the clock signal, and output a plurality of pieces of error data at a time corresponding to the unit interval; and an eye opening monitoring (EOM) circuit configured to compare the data with each of the plurality of pieces of error data to obtain an eye pattern of the data signal in the unit interval.
一种半导体装置包括:数据采样器,其被配置为接收具有第一频率的数据信号并且以具有高于第一频率的第二频率的时钟信号对数据信号进行采样,输出与数据信号的单位间隔对应的时间的数据;错误采样器,其被配置为以具有第二频率并且相位与时钟信号的相位不同的错误时钟信号对数据信号进行采样,输出与单位间隔对应的时间的多条错误数据;以及眼开度监测(EOM)电路,其被配置为比较数据与多条错误数据中的每一条以获得单位间隔中的数据信号的眼图。 |
