Notes:
1. VREF is expected to equal VCC/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 +/-1percent of the DC
value. Peak-to-peak AC noise on VREF may not excedd +/-2 persent of VREF. This measurement is to be taken at the nearest VREF bypass capacitor.
2. VTT in sot applied directly to the device. VTT is a system supply for signal terminaion resistors, is expected to be set equal to VREF and must track variations in the DC level of VREF.
