    • A phase interpolator is provided that, in one implementation, includes first and second interpolator modules, each having an output in communication with an output node. The first interpolator includes an input to receive a first plurality of input phase signals, and a selector to select one or more of the first plurality of input phase signals for interpolation at the output node of the phase interpolator. The second interpolator module includes an input to receive a second plurality of input phase signals, and a selector to select one or more of the second plurality of input phase signals for interpolation at the output node of the phase interpolator. Each of the selected ones of the first plurality of input signals and each of the selected ones of the second plurality of input signals are included in an interpolated output signal.
    • 提供了相位插值器,其在一个实现中包括第一和第二插值器模块,每个具有与输出节点通信的输出。 所述第一内插器包括用于接收第一多个输入相位信号的输入端,以及选择器,用于选择所述第一多个输入相位信号中的一个或多个用于所述相位插值器的输出节点处的插值。 第二内插器模块包括用于接收第二多个输入相位信号的输入端,以及选择器,用于选择第二多个输入相位信号中的一个或多个,用于在相位插值器的输出节点进行内插。 第一多个输入信号中的选定的输入信号和第二多个输入信号中的所选择的输入信号中的每一个被包括在内插的输出信号中。
