摘要： A differential line compensation apparatus is disclosed that has a first terminal to receive a first differential signal supplied by a first trace and a second terminal to receive a second differential signal supplied by a second trace. The apparatus has at least one detector to detect a first condition of a first signal at least related to the first differential signal, and a second condition of a second signal at least related to the second differential signal and to provide an output containing the results of the detections. A comparator is coupled to the at least one detector to receive and process the at least one output and to provide a control output. At least one delay controller receives the control output and applies a phase correction to a selected one of the first signal and the second signal. A corresponding method and system are also disclosed.

摘要： A system for hardware intelligent speed monitoring and auto-retract is disclosed. The system contains a monitoring device that monitors the TACH (Tachometer) output of motor driver. The device provides a trigger to the signal processor and a retract mechanism to retract the actuator when the spindle motor speed is unexpectedly much higher or lower than normal speed. The system DSP (Digital Signal Processor) is unaware of such occurrence.

摘要： An apparatus includes a bidirectional data line to couple to a device and an impedance to provide an impedance matching between the data line and the device. In some embodiments, when a direction of data flow in the data line is away from the device, the impedance is of a first impedance value, and when the direction of the data flow is toward the device, the impedance is of a second impedance value. In one embodiment, the second impedance value is substantially zero.

There is also provided a semiconductor chip, connectable to a data line, the semiconductor chip comprising the apparatus together with a data source or data receiver, as appropriate. There is also provided a method for controlling impedance matching between a data source or data receiver and a data line. The method comprises the steps of providing an impedance connected between the data source or data receiver and the data line; and continually adjusting the value of the impedance so as to control the relative impedances of the total source or total receiver and the data line.
