Variable speed phase interpolator
By adjusting the power supply voltage of the voltage-controlled oscillator and the delay of the phase interpolator in the phase-locked loop, the problem of clock signal waveforms not conforming to the intermediate phase at different clock frequencies was solved, achieving a good approximation of the clock signal and improving the reliability and efficiency of data transmission.

Abstract
A variable speed phase interpolator is provided. In some embodiments, a system includes: a phase-locked loop; a phase interpolator; and an interposer control circuit. The phase-locked loop may include an oscillator and an oscillator control circuit. The oscillator control circuit may be configured to set a value of an oscillator parameter to control an oscillation frequency of the oscillator. The interpolator control circuit may be configured to adjust a phase interpolator parameter of the phase interpolator based on a value of the oscillator parameter.
