    摘要: Embodiments include circuit devices and methods for re-clocking an input signal. In an embodiment, a circuit device includes a data storage element having a data input to receive a digital data stream having a first clock rate and including a clock input to receive a clock signal having a second clock rate. The data storage element further includes logic to adjust edge timing of transitions within the digital data stream based on the clock signal to produce a modulated output signal having a power spectrum with spectral nulls at a desired frequency and its harmonics without changing an average data rate.

    摘要: A line card for interfacing with a plurality of subscriber lines includes a plurality of data processors and a tone detector. Each of the data processors is associated with one of the subscriber lines. The tone detector is adapted to detect one of a plurality of activation tones on a selected subscriber line. The plurality of activation tones include a first activation tone having an active portion and a silent portion. The active and silent portions repeat periodically at a first frequency having a first period. A second activation tone has a phase reversal portion repeating at a second frequency and having a second period. The tone detector is further adapted to sequence between the subscriber lines at a predetermined interval. The predetermined interval is based on the first and second periods. The tone detector is adapted to signal the data processor associated with the selected subscriber line in response to detecting one of the activation tones.
