OUT1

2. The value of VIX is expected to equal 0.5*V DDQ of the transmitting device and must track variations in the

DC level of the same.

3. These parameters should be tested at the pin on actual components and may be checked at either the pin or

the pad in simulation. The AC and DC input specifications are relative to a VREF envelope that has been

bandwidth limited 20MHz.
