1. VDDQ tracks with VDD, VDDDL tracks with VDD. AC parameters are measured with VDD, VDDQ and VDDDL tied together.
2. 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 x VDDQ of
the transmitting device and VREF is expected to track variations in VDDQ.
3. Peak to peak ac noise on VREF may not exceed +/- 2% VREF (dc).
4. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors is expected to be set equal to VREF and must track variations in die dc
level of VREF.
5. VDDQ tracks with VDD, VDDL tracks with VDD. AC parameters are measured with VDD, VDDQ, and VDDL tied together.

1) Measurement Definition for Rtt(eff):
Apply VIHac and VILac to test pin separately, then measure current I(VIHac) and I(VILac) respectively.
Rtt(eff) = (VIHac - VILac) /( I(VIHac) - I(VILac))
2) Measurement Definition for VM:
Measure voltage (VM) at test pin (midpoint) with no load:
delta VM =(( 2* VM / VDDQ) - 1 ) x 100%
