    摘要: A random-access local network having multiple nodes provides data communication across residential wiring such as telephone line as a network medium, where each node accesses the network medium using discrete multi-tone (DMT) modulated symbols. The effects of amplitude and phase distortion of transmitted DMT symbols are overcome, without the necessity of complex equalizers, by differentially encoding data prior to transmission, and recovering the transmitted data by comparing phase differentials between consecutive symbol tones. Each transmitted symbol is composed of a plurality of tone signals, each tone signal modulated according to a constellation point in a complex domain. A transmitter modulates data, such as a bit-pair, to a new constellation point based on the value of the bit-pair and a prior position of a consecutively-preceding constellation point, such that the data is represented by the difference in positions between the consecutively-preceding constellation point and the new constellation point. The constellation points are then used to modulate a selected one of the tone signals. Although a receiver detecting the modulated tone signal may recover the transmitted constellation points at different absolute positions due to distortion on he network medium, the relative difference between the consecutively-preceding constellation point and the new constellation point is preserved, enabling the receiver to recover the transmitted data based on the relative difference in positions of the consecutive constellation points. Hence, entire bit stream can reliably transmitted using position changes between consecutive constellation points.

    摘要: An on-chip digital servo scheme for providing continuous calibration of integrated circuit on-chip time delay devices to provide real-time regulation against various parameter or environmental changes, such as processing, temperature and power supply variations. The techniques are particularly useful for semiconductor delay lines comprised of a selectable number of identical unit delay circuits having the same propagation time. This scheme constantly monitors the delay changes in the unit delay elements and calibrates the delay line by comparing the delay against a stable, crystal controlled reference clock period to determine, in each instance, how many unit delay elements in the delay line is needed to effectively delay the amount of time to equal the reference clock period. A real time digital pointer number is generated and updated while the device is in operation. This pointer can be used to inform or update other delay or time bases on the same integrated circuit substrate which are constructed from the same type of unit delay cell and which may choose to use a different number of unit delay cells. Accordingly, this scheme can then be used for various delay regulation purposes in and all-digital circuit, such as clock multiplication, pulse width regulation, and other applications where accurate, regulated, digital command controlled delay or time bases are needed.

    摘要: An optimum equalizer setting is determined for a signal equalizer in a network receiver by successively setting the equalizer to different predetermined settings, detecting timing correlation results between the equalized signal and a recovered clock in a digital phase locked loop, and determining a normalized distribution result for each of the predetermined equalizer settings based on the timing correlation results. The equalizer setting having the minimum normalized distribution result can then be selected as the optimum equalizer setting. Use of the correlation result from the phase locked loop enables the equalizer controller determining the optimum equalizer setting to determine the setting using a closed-loop setting. Hence, the equalizer controller can effectively determine the equalizer setting that causes the minimum amount of jitter in the phase locked loop.
