REF is expected to equal to 0.5*VCCQ of the transmitting device and to track variations in the DC level of the same. Peak-to-peak noise on VREF may not exceed +/-2 percent of the
DC value.

TT 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 the DC level of VREF
