CC and VCCQ are tied on the device.
REF is expected to equal VCCQ/2 of the transmitting device and to track variations in the DC level of the same. Peak-to-peak noise on VREF may not exceed ±1 percent of the DC value. Peak-to-peak AC noise
on VREF may not exceed ±2 percent of VREF. This measurement is to be taken at the nearest VREF bypass capacitor.
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.
