Note:
1. VDD and VDDQ must track each other. VDDQ must be less than or equal to VDD.
2. VREF is expected to equal to VDDQ/2 of the transmitting device and to track variations in the DC level of the same.
Peak to Peak AC noise on the VREF may not exceed +/-2% VREF(DC).
3. VTT of the transmitting device must track VREF of receiving device.
4. VDDQ tracks with VDD; VDDL tracks with VDD.
