Notes:

Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.

Functional operation should be restricted to recommended operating condition.

Exposure to higher than recommended voltage for extended periods of time could affect device reliability.

Notes:

1. VREF is expected to be equal to 0.5*VDDQ of the transmitting device, and to track variations in the DC level of the same.

Peak to peak noise on VREF may not exceed +/- 2% of the DC value.

2. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to

VREF, and must track variations in the DC level of VREF.

3. VID is the magnitude of the difference between the input level on CK and the input level of CK#.
