摘要： A replacement physical layer (PHY) for low-speed Peripheral Component Interconnect (PCI) Express (PCIe) systems is disclosed. In one aspect, an analog PHY of a conventional PCIe system is replaced with a digital PHY. The digital PHY is coupled to a media access control (MAC) logic by a PHY interface for PCIe (PIPE) directly. In further exemplary aspects, the digital PHY may be a complementary metal oxide semiconductor (CMOS) PHY that includes a serializer and a deserializer. Replacing the analog PHY with the digital PHY allows entry and exit from low-power modes to occur much quicker, resulting in substantial power savings and reduced latency. Because the digital PHY is operable with low-speed communication, the digital PHY can maintain sufficient bandwidth that communication is not unnecessarily impacted by digital logic of the digital PHY.
摘要翻译：公开了用于低速外围组件互连（PCI）快速（PCIe）系统的替代物理层（PHY）。在一个方面，常规PCIe系统的模拟PHY被数字PHY替换。数字PHY通过用于PCIe（PIPE）的PHY接口直接耦合到媒体访问控制（MAC）逻辑。在进一步的示例性方面，数字PHY可以是包括串行器和解串器的互补金属氧化物半导体（CMOS）PHY。用数字PHY替代模拟PHY允许更快地进入和退出低功耗模式，从而大幅节省功耗并缩短延迟时间。由于数字PHY可通过低速通信进行操作，因此数字PHY可以保持足够的带宽，通信不会受到数字PHY的数字逻辑不必要的影响。

摘要： Methods and apparatus for provision of a low power, low frequency squelch break protocol are described. In some embodiments, a fixed or variable time transmitter LFPS (Low Frequency Periodic Signaling) mechanism may be used that does not require a handshake and therefore much simpler in implementation than USB3 (Universal Serial Bus 3.0), for example. Also, an embodiment does not require a link common mode to be established and therefore may be optimized to support shorter durations for effecting exit from an electrical idle state that may be established via power-gating, for example. Other embodiments are also disclosed.
摘要翻译：描述了提供低功率，低频静噪中断协议的方法和装置。在一些实施例中，例如可以使用固定或可变时间发射机LFPS（低频周期性信令）机制，其不需要握手，因此比USB3（通用串行总线3.0）简单得多。而且，实施例不需要建立链路共同模式，因此可以被优化以支持更短的持续时间，以实现例如通过电源门控建立的电空闲状态的退出。还公开了其他实施例。
