摘要： A network device is disclosed that may automatically detect the working mode of an associated communications link by searching an incoming data stream for a pattern including at least a predetermined number of continuous ones or zeros. The device is initialized to operate in a first mode compliant with 1000Base-X protocols. A SERDES associated with encoding the data stream, when operating in the first mode, ensures that there are no more than five continuous ones or zeros in the data stream. Thus, if the data stream contains the pattern of six or more continuous ones or zeros, then occurrence of the pattern results from oversampling the data stream, and thus the data rate of the network device is higher than the data rate of the communications link.
摘要翻译：公开了一种网络设备，其可以通过搜索输入数据流来自动检测相关联的通信链路的工作模式，所述模式包括至少预定数量的连续1或零。该器件被初始化为符合1000Base-X协议的第一模式。当在第一模式下操作时，与编码数据流相关联的SERDES确保数据流中不超过五个连续的或零。因此，如果数据流包含六个或更多个连续的或零的模式，则由于对数据流进行过采样而产生模式，因此网络设备的数据速率高于通信链路的数据速率。

The method includes establishing communication between the MAC and the PHY via a first serial link in accordance with a Serializer Deserializer (SERDES) protocol.

摘要： A method and apparatus for enabling low power idle (LPI) signaling for Ethernet transceivers operating in legacy modes are disclosed that allow a high speed transceiver to retain energy efficient Ethernet (EEE) functionality even when the transceiver is operating in a slower speed mode. In some embodiments, an Ethernet device may enter an LPI mode upon receiving a regular LPI signal when its media independent interface (MII) is operating at a first transmission rate, and may enter the LPI mode upon receiving a modified LPI signal when the MII is operating at a second transmission rate that is slower than the first transmission rate.
