    • Self-timed interfaces and methods are provided for interfacing different timing domains. These self-timed interfaces receive a strobe signal from a component operating under a first clock domain. A first signal path of the self-timed interface couples the strobe signal to a receiver that samples data of data line under control of the strobe signal. A second signal path of the self-timed interface couples the strobe signal to an interface circuit through a hysteresis-based element. The interface circuit, under control of an output of the hysteresis-based element along with a clock signal that originates under a second clock domain, generates an interface enable signal for use in controlling data transfers between the different clock domains.
    • 提供自定义接口和方法来连接不同的定时域。 这些自定时接口从在第一时钟域下运行的组件接收选通信号。 自定时接口的第一信号路径将选通信号耦合到在选通信号的控制下采样数据线的数据的接收机。 自定时接口的第二信号路径通过基于滞后的元件将选通信号耦合到接口电路。 接口电路在基于滞后的元件的输出的控制下以及起始于第二时钟域的时钟信号产生用于控制不同时钟域之间的数据传输的接口使能信号。
