METHOD FOR PERFORMING PHASE SHIFT CONTROL FOR TIMING RECOVERY IN AN ELECTRONIC DEVICE, AND ASSOCIATED APPARATUS |
摘要 |
A method for performing phase shift control for timing recovery in an electronic device and an associated apparatus are provided, where the method includes: generating an output signal of an oscillator, wherein a phase shift of the output signal of the oscillator is controlled by selectively combining a set of clock signals into the oscillator according to a set of digital control signals, and the set of clock signals is obtained from a clock generator, wherein the phase shift corresponds to the set of digital control signals, and the set of digital control signals carries a set of digital weightings for selectively mixing the set of clock signals; and performing timing recovery and sampling on a receiver input signal of a receiver in the electronic device according to the output signal of the oscillator to reproduce data from the receiver input signal. |
