Note : 1. VID is the magnitude of the difference between the input level on CK and the input on CK.
2. The value of V_IX 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 pim on actual components and may be checked at either the pin or the pad in
simulation. the AC and DC input specificatims are refation to a Vref envelope that has been bandwidth limited 20MHz.
