摘要： As disclosed herein, a microelectronic circuit and method are provided for improving signal integrity at a transmission line. The circuit includes a programmably adjustable impedance matching circuit which is coupled to a transmission line which includes a programmably adjustable inductive element. The programmably adjustable impedance matching circuit is desirably provided on the same chip as a receiver or transmitter to which the transmission line is coupled, or alternatively, on an element packaged together with the chip that includes the receiver or transmitter. The impedance of the programmably adjustable impedance matching circuit is adjustable in response to control input to improve signal integrity at the transmission line.

摘要： Apparatus and method for counteracting high frequency attenuation of a differential input data signal as the signal is conducted through a data link. A differential input data signal is transmitted from a transmitter to a receiver through a data link. The data eye of the differential input data signal is modified at the transmitter in response to feedback from the receiver where the extent of the data eye of the differential input data signal, after being conducted through the data link, is determined. The feedback to the transmitter, dependent on the determination of the extent of the data eye, controls the data eye at the transmitter and the equalization of the differential input data signal by adapting the differential input data signal to anticipate high frequency attenuation of the differential input data signal in the data link.

摘要： A transmitter for driving a transmission medium employs pre-distortion to predistort the signals leaving the driver so that they will have an acceptable shape when they reach their destination and have been distorted by imperfections in the transmission medium. The change to pulse height is accomplished by means of a current steering unit that directs a controllable amount of current into the line for each pulse while maintaining the total sum of current that is generated constant in order to reduce noise. Control coefficients for the current steering unit are manipulated in an nxm register that automatically maintains the total number of bits constant while bits are moved from a location that controls a first current driver to a location that controls a second current driver with different properties.

摘要： A voltage controlled oscillator (VCO) is provided which includes a threshold level setting circuit operable to set a lower variable threshold level and to set an upper variable threshold level. The VCO includes a frequency band selection unit operable to adjust a frequency band setting of the VCO to one of a plurality of frequency band settings. The VCO further includes a comparator operable to determine whether a control voltage of the VCO falls between the lower threshold level and the upper threshold level. The VCO further includes a threshold adjustment and calibration circuit operable to maintain the frequency band setting when the control voltage falls between the lower and upper threshold levels. Otherwise, when the control voltage lies below the lower threshold level, the lower threshold level is adjusted downward and the upper threshold level is adjusted upward, and when the control voltage lies above the upper threshold level, the frequency band selection is increased to a next higher frequency band.
