    摘要: A clocking scheme is provided which uses an external clock signal having a frequency F, and generates an internal master clock signal equal having a frequency lower than (e.g., 1/2) F. The internal master clock signal operating at, for example, half the speed of the external clock is routed throughout a device to components on the device requiring a clock signal (e.g., input or output buffers in a synchronous memory product). A stream of narrow pulses corresponding to rising and falling edges of the internal master clock signal are locally generated for those components which require a clock signal at full frequency. This stream of narrow pulses has a frequency of F.

    摘要: A data processing system (10) capable of generating an output waveform (22) that has enhanced pulse width resolution. In one form, the system uses a counter (34) which is incremented by an input clock (20) running at an operating frequency of the system. Instead of incrementing the counter (34) by one, the counter (34) is incremented by a power of two so that the counter (34) appears to be counting a power of two faster. However, in order to increase the effective resolution of the counter (34) , the second edge of the output waveform (22) must be correctly adjusted depending on the desired duty cycle and period. The end result is a counter (34) that can produce a power of two greater resolution while still using the operating frequency of the system as an input clock (20).

    摘要: A pulse generator for generating an output pulse which is synchronized to an internal clock pulse includes a detector latch circuit (24), a master latch (12), a clocked latch (14), a first clocked half-latch (16), and an output logic circuit (18). The detector latch (24) is responsive only to the positive edge of the asynchronous pulse of a varying width for generating a trigger signal which is latched to a low logic level. The master latch (12) is responsive to the trigger signal for generating a first latched signal which is latched to a high logic level. The clocked latch means (14) is responsive to the first latched signal and a first internal clock pulse signal for generating a second latched signal which is latched to a high logic level. The first clocked half-latch (16) is responsive to the second latched signal and a second internal clock pulse signal for generating a control signal. The output logic circuit (18) is responsive to the first internal clock pulse signal and the control signal for generating an output pulse signal which is synchronized to the first internal clock pulse signal when the control signal is at a low logic level. A clearing circuit (19) is provided and is responsive to the control signal and the first internal clock pulse signal for generating a clearing signal which resets the first latched signal to a low logic level at the output of the master latch.

    摘要: In digitalen Nachrichtenübertragungssystemen werden die übertragenen Digitalsignale mit Leitungsentzerrern rege­neriert. Da bei digitalen Taktrückgewinnungseinrichtungen höhere Anforderungen an die Entzerrung gestellt werden ist es notwendig, die Impulsbreiten nochmals zu entzerren.
    Der Beginn der Impulse des entzerrten Digitalsignals (D3) wird aus den vorderen Flanken der zu entzerrenden Impulse des Digitalsignals (D2) und das Ende der Impulse des ent­zerrten Digitalsignals (D3) aus den vorderen Flanken der Impulse eines Daten-Hilfstakts (DHT) abgeleitet. Dieses Verfahren läßt sich beispielsweise in einer integrierten Schaltung mit zwei D-Flipflops (22,23) durchführen, die die Impulse von einem JK-Flipflop (26) gesteuert abwechselnd verarbeitet. Dadurch lassen sich auch Digitalsignale (D2) einer Bitrate gleich oder größer 34 Mbit/s verarbeiten.

    摘要: A method and a corresponding device for providing a delay value of a communication electronic unit. A digital input signal is delayed by a delay element. The input and the output signals of the delay element are sampled and the sampled signals are compared. A mismatch counter is incremented when the amplitudes of the sampled signals are not equal and a signal transition counter N is incremented when the input signal transitions. The provided delay value is proportional to the mismatch counting value, proportional to the length of the sampling intervals and inversely proportional to the signal transition counting value.
