Claim:
1. A method performed in a time interleaved receiver comprising: generating a plurality of clocks, each one of the plurality of clocks generated to have the same clock frequency but a different clock phase; determining a plurality of intersymbol interference (ISI) values, one for each of the plurality of clocks, by: for each clock of the plurality of clocks, sampling a signal using the clock to obtain a sampled signal and determining a value representing ISI based on the sampled signal; adjusting a clock phase of at least one of the plurality of clocks in response to at least one of the plurality of ISI values being different from a reference ISI value; wherein said adjusting the clock phase of at least one of the plurality of clocks comprises adjusting a clock phase of a selected one of the plurality of clocks in a direction dependent upon whether an ISI value associated with the selected one of the plurality of clocks is less than or greater than the reference ISI value.
