    • In described embodiments, a transceiver supports two or more rates using an oversampling clock and data recovery (CDR) circuit sampling high rate data with a predetermined CDR sampling clock. A timing recovery circuit detects and accounts for extra or missing samples when oversampling lower rate data. An edge detector detects each actual data symbol edge and provides for an edge decision offset in a current instant's block of samples. An edge error is generated from the previous instant's actual and calculated edges; and an edge distance between actual edges of the current and previous instants is generated. Filtered edge distance and error are combined to generate a calculated edge position for the data symbol edge for the current instant. The edge decision offset is applied to the current calculated edge position to identify a sample value to generate a decision for the data symbol to detect the current data value.
    • 在所描述的实施例中,收发器支持使用过采样时钟和数据恢复(CDR)电路采用具有预定CDR采样时钟的高速率数据采样的两个或更多个速率。 定时恢复电路检测并考虑过采样较低速率数据时的额外或缺失样本。 边缘检测器检测每个实际数据符号边缘并提供当前时刻的样本块中的边缘判定偏移。 从前一时刻的实际和计算边缘产生边缘错误; 并且生成当前和前一时刻的实际边缘之间的边缘距离。 滤波边缘距离和误差被组合以产生用于当前时刻的数据符号边缘的计算边缘位置。 边缘判定偏移被应用于当前计算的边缘位置以识别采样值,以产生用于数据符号来检测当前数据值的决定。
