摘要
A method and device for dynamically updating a phase interpolator circuit module using a phase update circuit module. The method can include interpolating a set of input clock phases based on a phase interpolator code input and sequentially updating the rising edge generator and falling edge generator starting from a synchronizer update signal. The dynamic sequential update involves disabling a rising edge ramp signal while updating a rising edge interpolator and generating old clock out falling edge according to an old phase interpolator code input, disabling a falling edge ramp signal while updating a falling edge interpolator, enabling the rising edge ramp signal and generating a new clock out rising edge according to a new phase interpolator code input, and enabling the falling edge ramp signal and generating a new clock out falling edge according to the new phase interpolator code input.
