    • An apparatus for providing time adjustment of an input signal includes a coarse timing digital-to-analog converter (DAC), a replica delay element and an interpolator. The coarse timing DAC has multiple delay settings for providing a coarse timing adjustment of the input signal, and outputs a first delayed signal by delaying the input signal by a first delay time corresponding to a selected setting of the multiple delay settings. The replica delay element receives the first delayed signal from the coarse timing DAC and outputs a second delayed signal by delaying the first delayed signal by a predetermined second delay time. The interpolator blends either the input signal and the first delayed signal or the first delayed signal and the second delayed signal for providing a fine timing adjustment of the input signal, and outputs a timing adjusted output signal including the coarse timing adjustment and the fine timing adjustment.
    • 用于提供输入信号的时间调整的装置包括粗略定时数模转换器(DAC),复制延迟元件和内插器。 粗定时DAC具有多个延迟设置,用于提供输入信号的粗略定时调整,并且通过将输入信号延迟与对应于多个延迟设置的所选设置的第一延迟时间来输出第一延迟信号。 复制延迟元件从粗定时DAC接收第一延迟信号,并通过将第一延迟信号延迟预定的第二延迟时间来输出第二延迟信号。 内插器将输入信号和第一延迟信号或第一延迟信号和第二延迟信号混合,以提供输入信号的精细定时调整,并输出包括粗略定时调整和精细定时调整的定时调整输出信号 。

    • The problem of undesired power consumption in an oscillator during "stop" periods of a device (35) is addressed by providing the oscillator in apparatus external to the device, the apparatus including a current sensor sensing current in a line between the apparatus and the device, the line (26) communicating an oscillator "clock" signal. If the device enters a "stop" state the current flow during certain half-cycles of the oscillation is relatively low compared to the current flow in the "no-stop" state. In response to a relatively low current, the apparatus halts oscillation (33). Later, when the device exits the "stop" state, current flow increases in the line, and the apparatus resumes oscillation, thereby resuming the communication of the clock signal to the device. Alternatively the apparatus monitors two oscillator lines by means of an XOR gate, powering down the oscillator when the XOR output goes low and restoring the oscillator when the XOR output goes high.
