Abstract
A valid data strobe detection technique detects a valid data strobe contained within a strobe signal by first determining whether a measured voltage level of the strobe signal is above or below a preselected threshold level. A time period in which the measured voltage level is continuously one of either above or below the preselected threshold level is then measured and a valid data strobe is detected upon the measured time period being greater than a preselected period of time. A comparator may be used to determine whether the measured voltage level of the strobe signal is above or below the preselected threshold level and a sample and hold unit may be used to measure the time period in which the strobe signal is one of either above or below the preselected threshold level.
