    摘要: In a variable delay circuit comprising a high-speed clock generator (100) receiving a trigger signal (10a) and outputting a pulse signal after a desired time interval from rising of the trigger signal (10a) and a coarse delay signal generator (500), the high-speed clock generator (100) comprises a rising edge detector (11) receiving the trigger signal (10a), detecting a rising edge of the trigger signal (10a), and outputting an edge detecting pulse (11a) having a time interval, and an asynchronous reset oscillator (12) receiving the edge detecting pulse (11a), being reset at rising of the edge detecting pulse (11a), and starting to generate a high-speed clock (12a) at falling of the edge detecting pulse (11a). Therefore, the high-speed clock generator (100) for the variable delay circuit is realized without using analog circuits. Further, since the high-speed clock generator (100) includes no PLL, it is not necessary to provide analog circuits, such as charge pump and VCO, on a digital LSI and, therefore, special considerations for the analog circuits are dispensed with.

    摘要: A method and apparatus for recovering the phase of a signal (403) which may change at periodic intervals is disclosed which comprises gated variable frequency oscillators (405,411). These results are obtained in an illustrative embodiment of the present invention in which an incoming signal (403) is fed into a gated oscillator (405) and the complement of the incoming signal is fed into a matching gated oscillator (411). Advantageously, the respective outputs of the two oscillators are fed into a Boolean NOR gate (417). When the gated oscillators are designed to oscillate at the frequency of the incoming signal, the output waveform will have a bounded phase relationship with respect to the incoming signal.

    摘要: Es wird eine Vorrichtung zur Rückgewinnung eines bestimmten Taktes aus einer mit diesem Takt getakteten Signal- folge, insbesondere einer Zufallsfolge, beschrieben. Die Vorrichtung besteht aus einem Taktgenerator, der von sich aus Taktsignale in einem Takt erzeugt, dessen Taktlänge auf den bestimmten Takt der Signal-folge abgestimmt ist, und der durch ein oder mehrere bestimmte Signale der Signalfolge extern triggerbar ist, um dadurch seinen Takt mit dem Takt der Signalfolge zu synchronisieren. Der Taktgenerator besteht vorzugsweise aus einem monostabilen Multivibrator, dessen Ausgangs-signale verzögert auf den als Triggereingang dienenden Eingang rückgekoppelt werden.

    摘要: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. A first transition may be detected in a signal carried on a data lane of a data communications link or carried on a timing lane of the data communications link and an edge may be generated on a receiver clock signal based on the first transition. Data may be captured from the data lane using the receiver clock signal. The timing lane may carry a clock signal, a strobe signal or another signal providing timing information. The strobe signal may transition between signaling states when no state transition occurs on any of a plurality of data lanes at a boundary between consecutive data periods.
