Notes:
1
VREF is expected to equal to 0.5*VCCQ 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 percent 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#.

Notes:
Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceed.
Functional ioeration should be restricted to recommended operation conditions.
Exposing to higher than recommended voltage for extended periods of time could affect device reliability.
