Abstract
Apparatus and methods for clock duty cycle correction and deskew are provided. In certain embodiments, a clock distribution circuit includes a clock driver that provides a differential clock signal to a clock slicer over a pair of transmission lines. The clock distribution circuit further includes a resistor-inductor-capacitor (RLC) tuning circuit for providing termination between the pair of transmission lines and a differential input to the clock slicer. The RLC tuning circuit includes a pair of resistor digital-to-analog converters (resistor DACs or RDACs) coupled to the pair of transmission lines and a pair of controllable inductor-capacitor (LC) circuits coupled to the pair of transmission lines.
