49 / 250 page  Intel® 6400/6402 Advanced Memory Buffer Datasheet 49 Electrical, Power, and Thermal 4.4.9 Write Preamble Duration The write preamble duration is the measurement from the point when DQS and DQS start to be driven, to the crossing point of DQS and DQS. Typically, to determine when DQS and DQS are starting to be driven, timing measurements are made at 0.5xVCC +/ - 50 mV, and 0.5xVCC +/- 100 mV, and then the measurements are linearly extrapolated back to 0.5xVCC. 4.4.10 Write Postamble Duration The write postamble duration is the measurement from the crossing point of DQS and DQS, to the point where DQS and DQS start to go into a high impedance state. Typically, to determine when DQS and DQS are starting to go into a high impedance state, for DQS, timing measurements are made at Vlow + 50 mV, and Vlow + 100 mV, and then the measurements are linearly extrapolated back to Vlow. For DQS, timing measurements are made at Vhigh - 50 mV, and Vhigh - 100 mV, and then the measurements are extrapolated back to Vhigh. Figure 4-8.
