Notes: 1. VDDQ must not exceed the level of VDD.

2. VIL (min) is acceptable -1.5V AC pulse width with ð 5ns of duration.

3. The value of VREF is approximately equal to 0.5VDDQ.

Notes: 1. VID is the magnitude of the difference between the input level on CK and the input on CK.

2. The value of VIX is expected to equal 0.5*VDDQ of the transmitting device and must track variations in the DC level of the

same.
