NOTE:
1. VCC and VCCQ must track each other. VCCQ must be less than or equal to VCC.
2. VREF 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 (non-common mode) on VREF may not exceed ±1percent of the DC value. Peak-to-peak AC noise on VREF may
not exceed ±2 percent of VREF (DC). This measurement is to be taken at the nearest VREF bypass capacitor.
3. 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 the DC level of VREF.
4. VCCQ tracks with VCC; VCCL tracks with VCC.
