Abstract

The present invention provides a circuitry including a PLL and a CDR circuit, wherein the CDR circuit includes a phase detector, a loop filter, a SSC demodulator, a control code generator and a phase interpolator. The PLL is configured to generate a clock signal with SSC modulation and a SSC direction signal. The phase detector is configured to compare phases of an input signal and an output clock signal to generate a detection result, wherein the input signal is with SSC modulation. The loop filter is configured to filter the detection result to generate a filtered signal. The SSC demodulator is configured to receive the SSC direction signal to generate a control signal. The control code generator is configured to generate a control code according to the filtered signal and the control signal to control the phase interpolator to use the clock signal to generate the output clock signal.
