N o t e s :  
1. VCC 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 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.  
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 track with VCC.
