摘要： In preferred embodiments, an adaptive equalization circuit including at least two equalization filters (each for equalizing a signal transmitted over a multi-channel serial link) and control circuitry for generating an equalization control signal for use by all the filters. The control circuitry generates the control signal in response to an equalized signal produced by one of the filters, and asserts the control signal to all the filters. Preferably, one filter generates an equalized fixed pattern signal in response to a fixed pattern signal (e.g., a clock signal), each other filter equalizes a data signal, and the control circuitry generates the control signal in response to the equalized fixed pattern signal. In other embodiments, the invention is an adaptive equalization circuit including an equalization filter and circuitry for generating a control signal for the filter in response to a signal indicative of a predetermined fixed pattern, a receiver including an adaptive equalization circuit, a system including such a receiver, and a method for adaptive equalization of signals received over a multi-channel serial link.

摘要： A cable including circuitry for asserting information to a user or external device and a system including such a cable. The cable can include conductors, a memory storing cable data, and circuitry configured to respond to a request received on at least one of the conductors by accessing at least some of the cable data and asserting the accessed data serially to at least one of the conductors (e.g., for transmission to an external device). Other aspects of the invention are methods for accessing cable data stored in a cable and optionally using the data (e.g., to implement equalization). The cable data can be indicative of all or some of cable type, grade, speed, length, and impedance, a date code, a frequency-dependent attenuation table, far-end crosstalk and EMI-related coefficients, common mode radiation, intra pair skew, and other information. The cable can include a radiation-emitting element and circuitry for generating driving signals for causing the radiation-emitting element to produce an appropriate color, brightness, and/or blinking pattern.

摘要： A method, apparatus and system for pre-authenticating ports is disclosed. In one embodiment, an active port facilitating communication of media content between a transmitting device and a receiving device is identified, while the active port are associated with a first High-Definition Content Protection (HDCP) engine. Then, inactive ports that are in idle mode serving as backup ports to the active port are identified, while the inactive ports are associated with a second HDCP engine. Pre-authentication of each of the inactive ports is performed so the pre-authenticated inactive ports can subsequently replace the active port if a port switch is performed.

摘要： A scheme for reducing jitter in high-speed digital communication by adaptively controlling the loop bandwidth of a receiver PLL to reduce the relative jitter between the recovered data and clock. The scheme uses phase pointer activity to represent the relative jitter. The phase pointer activity is measured and used to control the receiver PLL loop bandwidth. The receiver PLL loop bandwidth is repeatedly incremented or decremented by a step size based on the comparison between a newly measured activity value and the old activity value, until the phase pointer activity reaches a minimum. Because the PLL performance requirement of the transmitter can be relaxed, compatibility with legacy transmitters and multi-vendor transmitters is enhanced. Because tight control of fabrication process parameters of PLLs may be relaxed, the fabrication yield may also be improved.
摘要翻译：通过自适应地控制接收机PLL的环路带宽以减少恢复的数据和时钟之间的相对抖动来减少高速数字通信中的抖动的方案。该方案使用相位指针活动来表示相对抖动。测量相位指针活动并用于控制接收机PLL环路带宽。基于新测量的活动值和旧活动值之间的比较，接收机PLL环路带宽被重复地增加或减小步长，直到相位指针活动达到最小值。因为发射机的PLL性能要求可以放宽，与传统发射机和多厂商发射机的兼容性得到增强。由于PLL的制造工艺参数的紧密控制可以被放宽，所以也可以提高制造成品率。

摘要： A method of transmitting data in a system including at least one data channel and a separate clock channel is disclosed. The method involves combining a clock signal to be transmitted on the clock channel with a data signal to generate a combined clock and data signal. In one embodiment, the data signal has been generated from data words using an encoding scheme that shifts an energy spectrum of the data signal away from an energy spectrum of the clock signal. In another embodiment, the clock signal has a plurality of pulses each having a front edge and a back edge, and the data signal is modulated onto the clock signal by moving at least one edge (i.e. front or back or both) of the plurality of pulses, thereby to create a combined clock and data signal.
