Abstract: Embodiments of the present disclosure provide an in-band process to inform an external repeater of a desired new configuration or mode of operation. After negotiation of rate and other information during an auto-negotiation routine, a network node sends configuration information to a network element, such as an external network repeater.
Abstract translation: 本公开的实施例提供了一种带内过程，以向外部中继器通知所需的新配置或操作模式。 在自动协商程序中协商速率和其他信息之后，网络节点将配置信息发送到诸如外部网络中继器的网元。

Abstract: An apparatus and method is disclosed to compensate for one or more offsets in a communications signal. A communications receiver may carry out an offset adjustment algorithm to compensate for the one or more offsets. An initial search procedure determines one or more signal metric maps for one or more selected offset adjustment corrections from the one or more offset adjustment corrections. The offset adjustment algorithm determines one or more optimal points for one or more selected offset adjustment correction based upon the one or more signal maps. The adaptive offset algorithm adjusts each of the one or more selected offset adjustment corrections to their respective optimal points and/or each of one or more non-selected offset adjustment corrections to a corresponding one of a plurality of possible offset corrections to provide one or more adjusted offset adjustment corrections. A tracking mode procedure optimizes the one or more adjusted offset adjustment corrections.

Abstract: A device for transmit (TX) training a remote link partner (LP) includes a TX retimer module adjacent to a TX port of the device, and a receive (RX) retimer module adjacent to the TX retimer module. The RX retimer module copies first control and status data to the TX retimer module, and the TX retimer module provides second control and status data for TX training of the remote LP.

Abstract: Reference-less repeating circuits provide significant advantages over repeating circuits requiring external frequency references. These repeating circuits eliminate the need for external frequency references provide significant power, layout, and physical isolation advantages. Digitally controlled reference-less repeating circuits have a relatively narrow frequency detection range, but typically consume significantly less power than analog repeating circuits while providing data rate flexibility, particularly at lower data rates. Due to the narrow frequency detection range of digitally controlled reference-less repeating circuits, efficient frequency estimation techniques allow these circuits to quickly lock to an input signal, and provide an accurate repeated output signal.
Abstract translation: 无需外部频率参考的无需重复电路可提供超过重复电路的显着优点。 这些重复电路消除了对外部频率参考的需求，提供了显着的功率，布局和物理隔离优势。 数字控制的无参考中继电路具有相对较窄的频率检测范围，但是通常比模拟重复电路消耗明显更少的功率，同时提供数据速率灵活性，特别是在较低的数据速率下。 由于数字控制的无参考中继电路的窄频率检测范围，有效的频率估计技术允许这些电路快速锁定到输入信号，并提供准确的重复输出信号。
