控制采样设备的采样频率和采样相位的装置和方法
摘要：
一种从耦合到采样设备的均衡器生成的值控制该采样设备的采样频率和采样相位的方法，所述方法包括：生成由均衡器导出的值的复数表示的步骤，以及生成来自该均衡器的输出的判决表示的步骤。将该复数表示与该判决表示相关以获得采样误差估计。使用该采样误差估计来调整采样设备的采样频率和采样相位。
摘要（英）：

A method of controlling sampling frequency and sampling phase of a sampling device from a value generated by an equalizer coupled to the sampling device includes the steps of generating a complex representation of the value developed by the equalizer and generating a representation of a decision from an output of the equalizer. The complex representation and the decision representation are correlated to obtain a sampling error estimate. The sampling error estimate is used to adjust the sampling frequency and sampling phase of the sampling device.
