RECOMMENDED DC OPERATING CONDITIONS
All voltages referenced to VSS.
Notes:
OUTPUT ELECTRICAL CHARACTERISTICS AND OPERATING CONDITIONS
Differential AC Output Parameters
Note: The typical value of VOX(AC) is expected to be about 0.5 x VDDQ of the transmitting device and VOX(AC) is expected to
track variations in VDDQ. VOX(AC) indicates the voltage at which differential output signals must cross.

Peakto- 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.
