摘要： In a method for performing equalization of a communication system, a predetermined signal can be transmitted from a transmitter unit to a receiver unit in a downchannel direction on a transmission line, for example as a pair of differential signals which simultaneously transition in opposite directions on respective signal conductors of the transmission line. At the receiver unit, an eye opening of the signal received from the transmission line can be analyzed to determine equalization information. Equalization information can be transmitted from the receiver unit to the transmitter unit in an upchannel direction on the transmission line and be received at the transmitter unit. Using received equalization information, a transmission characteristic of the transmitter unit can be adjusted.

摘要： A data receiver is provided which includes a front end interface circuit having an alternating current (AC) transmission receiving mode and a direct current (DC) transmission receiving mode. The front end interface circuit includes an offset compensation circuit operable to compensate a DC voltage offset between a pair of differential signals input to the data receiver. The front end interface circuit further includes an AC/DC selection unit operable to switch between (a) the DC transmission receiving mode, and (b) the AC transmission receiving mode, such that the data receiver is operable in (i) the DC transmission mode in which the offset compensation circuit is disabled, (ii) the DC transmission mode in which the offset compensation circuit is enabled, (iii) the AC transmission mode in which the offset compensation circuit is disabled, and (iv) the AC transmission receiving mode in which the offset compensation circuit is enabled.

摘要： A method is provided for operating a transmitter integrated in a microelectronic element. In a calibration phase, a plurality of operational parameters are stored for controlling a frequency response of the transmitter under each of a plurality of corresponding operating conditions. Upon detecting an operating condition such as a temperature or power supply voltage level, the corresponding stored operational parameter is applied to the transmitter to control the frequency response.

摘要： A system for protecting a weak device operating in micro-electronic circuit that includes a high voltage power supply from high voltage over stressing prevents the weak device from failing during power-up, power-down, and when a low voltage power supply in a multiple power supply system is absent. The system includes a low voltage power supply detection circuit configured to detect circuit power-up, circuit power-down, and when the low voltage power supply is absent, and generate a control signal upon detection. The system further includes a controlled current mirror device configured to provide a trickle current to maintain a conduction channel in the weak device in response to the control signal received from the low voltage power supply detection circuit during circuit power-up, circuit power-down, and when the low voltage power supply is absent.
