Abstract
A method of receiving data. A plurality of data signals and clocking signals are received over a source synchronous communication channel. The plurality of data signals is strobed with the clocking signal at a plurality of coarse time offset delays (e.g., time offset delays spanning over a data bit period). The plurality of error rates associated with the strobing at the plurality of coarse time offset delays is determined. Strobing design of a transmitting component (e.g., edge-strobed, center-strobed, etc.) may be determined based on the plurality of error rates. The error rates of the plurality of data signals strobed with a plurality of time offset delays close to the determined strobing design of the transmitting component is calculated. A time offset delay is selected based on the error rates. The plurality of data signals can be strobed with the selected time offset delay to recover the transmitted data signals.
