Notes1. The swing of ±0.1 × VDDQ is based on approximately 50% of the static single-ended output high or

low swi

ng with a driver impedance of 34Ω and an effective test load of 25Ω to VTT = VDDQ/2 at each of the

differential outputs.

Notes2. The swing of ±0.2 × VDDQ is based on approximately 50% of the static single-ended output high or

low swing with a driver impeda

nce of 34Ω and an effective test load of 25Ω to VTT = VDDQ/2 at each of the

differential outputs.
