Notes: 1. The value of VREF may be selected by the user to provide optimum noise margin in the system. Typically

the value of VREF is expected to be about 0.5

×

VDDQ of the transmitting device and VREF are expected

to track variations in VDDQ.

2. Peak to peak AC noise on VREF may not exceed

±2%

VREF (DC).

3. VTT of transmitting device must track VREF of receiving device.

4. VDDQ tracks with VDD, VDDL tracks with VDD. AC parameters are measured with VDD, VDDQ and

VDDL tied together.
