  • Patent number: 11095426
    Abstract: Aspects of the disclosure provide a receiver for receiving data over a wired communication channel. The receiver includes an analog front end circuit, a pulse generation circuit and a voltage-controlled oscillator (VCO). The analog front end circuit receives an analog signal carrying data over the wired communication channel, and outputs a data signal with data bit transitions between voltage levels. The pulse generation circuit generates a pulse signal in response to the data bit transitions in the data signal. The voltage-controlled oscillator (VCO) generates an oscillation signal for providing sampling clocks for the data signal. The voltage-controlled oscillator aligns transitions in the oscillation signal to the pulse signal by forcing the oscillation signal to transit voltage levels in response to a pulse in the pulse signal.
