摘要： Resistors may be more accurately tuned by using an external resistor and comparing the value of an internal resistor to the value of the external resistor. The value of the internal resistor may be adjusted to match the value of the external resistor. Any number of on-chip resistors may then be matched and adjusted using the information obtained with respect to the first internal resistor.

摘要： An apparatus and method for aligning any number of multiple parallel channels of data signals according to a single clock is provided. The synchronization process is accomplished through the use of a First-In-First-Out (FIFO) principle and individual storage elements implementing the FIFO principle for each received data channel. Each channel's data signals are read into a corresponding storage element, maintained in order, and read out upon the assertion of read signals in synchronization with a designated single clock signal. The apparatus and method preferably uses indications of data ready to be read from a storage element implementing the FIFO principle and the presence of a master clock signal to activate the reading of the data from the corresponding storage element. Therefore, each data channel is fully aligned with the master clock signal. The clock-data alignment function may be implemented for a 100BASE-T4 receiver.

摘要： A transceiver module for coupling between cells in a distributed intelligence network and a twisted pair line. The module receives power from the line and provides power to its respective cell. At the end of transmitting a packet, the transceiver transmits a code violation, then an anti-code violation to dissipate energy in the line. This is followed by clamping the line for the dead time between packets. N transceivers may be connected (without a cell) to form a repeater. The transceiver module may be used in a network having free topology; that is, an ideal transmission line, with terminators is not needed.

摘要： In accordance with one embodiment of the present invention, a signal detect circuit may analyze an input signal before passing it on to a receiver. The analysis may be done outside of the data path to avoid affecting the data path speed or adding distortion or jitter. The positive and negative thresholds of the data may be checked to see if the numbers of positive and negative crossings are comparable. Random and bursty noise can be detected since such noise normally does not have comparable positive and negative crossings.
摘要翻译：根据本发明的一个实施例，信号检测电路可以在输入信号传送到接收器之前分析输入信号。分析可以在数据路径之外进行，以避免影响数据路径速度或增加失真或抖动。可以检查数据的正和负阈值以查看正和负交叉的数量是否可比。可以检测到随机和突发噪声，因为这种噪声通常不具有可比的正负交叉。
