Abstract: Serial data signal receiver circuitry for inclusion on a PLD includes a plurality of equalizer circuits that are connected in series and that are individually controllable so that collectively they can compensate for a wide range of possible input signal attenuation characteristics. Other circuit features may be connected in relation to the equalizer circuits to give the receiver circuitry other capabilities. For example, these other features may include various types of loop-back test circuits, controllable termination resistance, controllable common mode voltage, and a controllable threshold for detection of an input signal. Various aspects of control of the receiver circuitry may be programmable.

Abstract: Equalization circuitry may be used to compensate for the attenuation of a data signal caused by a transmission medium. The control circuitry for the equalization circuitry may generate control inputs for equalization stages that control the amount of gain provided to the data signal. A comparator may determine whether the gain from the equalization circuitry is less than or more than the desired amount of gain. A programmable up/down counter may adjust the counter value based on the output of the comparator. The counter value may be converted into one or more analog voltages using one or more digital-to-analog converters. These analog voltages may be provided to the equalization stages as control inputs. The control circuitry may also include hysteresis circuitry that prevents the counter value from being adjusted when the gain produced by the equalization stages is close to the desired amount of gain.

Abstract: PROBLEM TO BE SOLVED: To provide digital adaptation circuitry and method for programmable logic devices.
SOLUTION: This method provides for controlling equalization of an incoming data signal. The method includes detecting two successive differently valued bits in the data signal, determining whether transition in the incoming data signal between those bits occurs relatively late or relatively early, and increasing the equalization of the incoming data signal if it is relatively late.

Abstract: PROBLEM TO BE SOLVED: To provide an equalization circuit for appropriately compensating for attenuation caused by transmission media.SOLUTION: Data signals transmitted over transmission media suffer from attenuation caused by the transmission media. An equalization circuit (106) includes a plurality of stages (202) arranged in series to allow frequency responses of the stages (202) to be integrated together. Each stage (202) is programmable to insert a zero, thus causing the frequency response of the stage (202) to be increased in magnitude by 20 dB/decade. The frequency location of zero is also programmable to allow each stage (202) to contribute to a certain amount of a gain for a specific frequency. Each stage (202) is also programmable to determine the location of a pole for the reduction of high frequency noise and cross-talk cancellation.
