Abstract:
A method of performing clock recovery and equalizer coefficient estimation in a multi-channel receiver may include recovering, at a first clock recovery unit, a first clock signal associated with a first channel. The method may include estimating a first set of coefficients for a first equalizer associated with the first channel using the first clock signal. The method may include passing the first clock signal to a second clock recovery unit associated with a second channel. The method may also include recovering, at the second clock recovery unit, a second clock signal associated with the second channel using the first clock signal as a reference clock signal. The method may also include passing the first set of coefficients as initialization coefficients to a second equalizer associated with the second channel. The method may also include estimating a second set of coefficients for the second equalizer using the initialization coefficients.
