Notes
1. All voltages referenced to VSS and VSSQ must be same potential.
2. VID(DC) and VID(AC) are the magnitude of the difference between the input level on CK and the input level on CK .
3. The value of VIX is expected to be 0.5 * VDDQ and must track variations in the DC level of the same.
4. Any input 0V ≤ VIN ≤ VDD. All other pins are not tested under VIN = 0V.
5. Any output 0V ≤ VOUT ≤ VDDQ. DOUT is disabled.
