First-order loop control configuration for a phase-rotator based clock synchronization circuit
摘要：
An embodiment of the present invention is electronic circuitry for producing an I-phase quadrant pointer (FI) and a Q-phase quadrant pointer (FQ) by sampling a feed clock (IC) and a quadrature feed clock (QC), the circuitry comprises: a first quadrant detector (406, FIG. 5) for producing the Q-phase quadrant pointer in response to receipt of the feed clock and input data; a second quadrant detector (408, FIG. 5) for producing the I-phase quadrant pointer in response to receipt of the feed clock and the input data; and wherein the I-phase quadrant pointer and the Q-phase quadrant pointer can be utilized to determine the phase quadrant of the input data.
