Abstract: The present invention is directed to communication systems. According to embodiments of the present invention, a communication system includes at least two communication lanes and a skew management module. The skew management module generates a control current based on output test patterns of the two communication lanes. The control current is integrated and compared to a reference voltage by a comparator, which generates an analog offset signal. A PLL of one of the communication lanes generates a corrected clock signal that is adjusted using the analog offset signal to remove or adjust the skew between the communication lanes. The corrected clock signal is used for output data. There are other embodiments as well.

Abstract translation: 本发明涉及通信系统。 根据本发明的实施例，通信系统包括至少两个通信通道和偏斜管理模块。 偏斜管理模块基于两个通信通道的输出测试模式生成控制电流。 控制电流被积分，并通过比较器与参考电压进行比较，产生模拟偏移信号。 通信通道之一的PLL产生校正的时钟信号，其使用模拟偏移信号进行调整，以消除或调整通信通道之间的偏斜。 校正的时钟信号用于输出数据。 还有其它实施例。
