摘要： A PHY having a media independent interface (MII) providing connections to a MAC or to another PHY is disclosed. The invention provides a mechanism for connecting a first PHY with a second PHY, wherein the PHY may act as the media access control side of the MII. The system includes a selection means for selecting the mode of operation for the PHY, a MII for providing a synchronous digital interface carrying un-encoded data over separate transmit and receive paths and a translation entity for generating output enables for controlling the flow of the data, wherein the translation entity establishes in response to mode being selected a first flow of data for connecting the PHY to a Media Access Control entity or a second flow of data for connecting the PHY to a second PHY. The translation entity muxes data and control signals based upon the mode selection. A translation synchronization entity is provided. The synchronization entity may includes a 10 Mbps synchronization entity and/or a 100 Mbps synchronization entity. The MII receives a transmit and receive clock from a second PHY when the PHY is connected to a second PHY, and the translation synchronization entity synchronizes the internal clocks and the MII transmit and receive clocks. An interface to a 10 or 100 Mbps repeater entity is provided wherein the interface maps a transmit data path from the translation entity to the repeater entity and receive data paths from the repeater entity to the translation entity.

摘要： A Physical Layer Device is disclosed having power savings features operable during auto-negotiation for multiple technologies. Excessive power consumption is alleviated by decreasing the power required by the receiver(s) during parallel detection. The Physical Layer Device includes at least one port, with each port including a parallel detection receiver for receiving data and messages from a connected device, the data and messages including autonegotiation fast link pulses indicating a technology capability of the connected device, a cycler for enabling the parallel detection receiver for a fraction of an autonegotiation period and a controller for controlling the cycler. The enabling of the receiver for each port, whether a multiple or single port device, is staggered to prevent more than one receiver from being enabled at one time. Accordingly, the receivers are enabled for a brief period of time to check for the presence of the required signals, and then disabled for a much greater period of time before being enabled again. Further, the Physical Layer Devices contains multiple ports that can stagger the enabling of their receivers so that only one port's receiver is active at any given time.
摘要翻译：公开了一种物理层设备，其具有在多种技术的自动协商期间可操作的功率节省特征。通过在并行检测期间降低接收机所需的功率来减轻功耗过大。物理层设备包括至少一个端口，每个端口包括用于从连接的设备接收数据和消息的并行检测接收器，所述数据和消息包括指示所连接设备的技术能力的自动协商快速链路脉冲，用于启用的循环器用于一部分自动协商周期的并行检测接收器和用于控制循环仪的控制器。每个端口的接收器（无论是多个或单个端口设备）的启用是交错的，以防止一个以上的接收器被启用。因此，接收器被启用短时间以检查所需信号的存在，然后在再次被使能之前被禁用更长的时间段。此外，物理层设备包含多个端口，这些端口可能错开其接收器的使能，以便在任何给定时间只有一个端口的接收器处于活动状态。
