Abstract
In some embodiments, a phase detector receives a set of sampling clock signals and a data signal and compares each of the clock signals to the data signal. A clock selector selects an optimal sampling clock signal from the set of sampling clock signals based on a trend of a relationship between the clock signals and the data signal. Other embodiments are described and claimed.
Claims30
A method comprising:
- determining a trend in a relationship between clock signals and received data based on information included in the received data;
- and
- identifying a first clock as an optimal sampling clock for the data based on the trend.
Apparatus comprising:
- a phase detector to receive a set of sampling clock signals and a data signal and to compare each of the clock signals to the data signal;
- and
- a clock selector to select an optimal sampling clock signal from the set of sampling clock signals based on a trend of a relationship between the clock signals and the data signal.
A system comprising:
- a receiver to receive the data signal from a transmitter;
- a clock generator to generate a set of sampling clocks;
- a clock determination module connected to the receiver and clock generator to compare the data signal to the set of clocks to determine an optimal sampling clock based on a trend in the relationship of the data signal to the clocks;
- and
- a sampling system to sample the data with the optimal sampling clock.
