Notes1. The swing of ±0.1 × VDDQ is based on approximately 50% of the static single-ended output high or  
low swing with a driver impedance of 34Ω and an effective test load of 25Ω to VTT = VDDQ/2 at each of the  
differential outputs.

Notes1. Measured using an effective test load of 25Ω to 0.5* VDDQ at each of the differential outputs.  
Notes2. For a differential slew rate in between the listed values, the VOX value may be obtained by linear  
interpolation.  
Notes3. The DQS, /DQS pins under test are not required to be able to drive each of the slew rates listed in the  
table; the pins under test will provide one VOX value when tested with specified test condition. The DQS and  
/DQS differential slew rate when measuring VOX determines which VOX limits to use.
