主权项

1. A method comprising:
receiving a signal by a delay line; receiving a first clock signal and phase interpolating therefrom a second clock signal; selecting the first clock signal or the second clock signal in response to a control signal and outputting the selected first clock signal or second clock signal to a readout circuit; and receiving output signals from the delay line using the readout circuit while clocking the readout circuit at the selected first clock signal or second clock signal.
