Notes:

1. 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..
