Figure 8. Read Data sample window depend on the number of Tap delay
The position of the tdata_valid window is depend on the clock / data flight time on the board. The MDQS
signal indicate if the read data are valid. If the controller is not able to detect a valid MDQS signal on the
sample time (sample position A) then the controller will look for valid MDQS / data on the next edge of
the MEM_CLK signal (sample position B). Depend on the board travel time, different working tap delay
configurations are possible. For a fast connection the data will be sampled with the next edge of
MEM_CLK, this shows Figure 8, sample position A. With a longer connection maybe two sample
positions are possible. Figure 8 shows a example with two working sample position (A and B). With a
bigger board delay only sample position B will be possible.
The equation below shows how to calculate the upper and lower limit. The right Tap delay number is
selected, when the possible max and min sample timing is within the memory data valid window.
tdata_sample_max = max((1.55 + TapNum * 0.095), (1.74 + TapNum * 0.045))
tdata_sample_min = min((1.55 + TapNum * 0.095), (1.74 + TapNum * 0.045))
