Note :
Permanent device damage may occur if ABSOLUTE MAXIMUM RATINGS are exceeded.
Functional operation should be restricted to recommend operation condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability

Notes 1. V
REF
is expected to be equal to 0.5*V
DDQ
of the transmitting device, and to track variations in the DC level of the same. Peak-to-
peak noise on V
REF
may not exceed 2% of the DC value
2.V
TT
is not applied directly to the device. V
TT
is a system supply for signal termination resistors, is expected to be set equal to
V
REF
, and must track variations in the DC level of V
REF
3. V
ID
is the magnitude of the difference between the input level on CK and the input level on CK.
