摘要： Systems and methods are provided using dynamically adjustable differential output drivers. Integrated circuits such as programmable logic devices may be provided with adjustable differential output drivers for transmitting high-speed data to other integrated circuits. The peak-to-peak output voltage and common-mode voltage of the output drivers may be adjusted. Dynamic control circuitry may be used to control the settings of current sources, programmable resistors, and voltage source circuitry in the adjustable differential output driver automatically in real time. The adjustable components in the differential output driver may be adjusted by the dynamic control circuitry based on feedback information received from the integrated circuit to which the data is transmitted.

摘要： In a programmable logic device with a number of different types of serial interfaces, different power supply filtering schemes are applied to different interfaces. For interfaces operating at the lowest data rates—e.g., 1 Gbps—circuit-board level filtering including one or more decoupling capacitors may be provided. For interfaces operating at somewhat higher data rates—e.g., 3 Gbps—modest on-package filtering also may be provided, which may include power-island decoupling. For interfaces operating at still higher data rates—e.g., 6 Gbps—more substantial on-package filtering, including one or more on-package decoupling capacitors, also may be provided. For interfaces operating at the highest data rates—e.g., 10 Gbps—on-die filtering, which may include one or more on-die filtering or regulating networks, may be provided. The on-die regulators may be programmably bypassable allowing a user to trade off performance for power savings.

摘要： Methods and circuits for automatic adjustment of equalization are presented that improve the quality of equalization for input signals with varying amplitudes. The methods and circuits may be used in Decision Feedback Equalization (DFE) circuits to maintain a constant equalization boost amplitude despite variations in input signal amplitude. The equalization circuitry measures the amplitude of the equalization input signal and computes tap coefficients to maintain a desired level of boost amplitude. Tap coefficients may be automatically adjusted by the equalization circuitry.
