Note: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is stress
rating only, and functional operation of the device at these or any other conditions above those indicated in the operational secti
ons of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

1. Inputs are not recognized as valid until V
REF
stabilizes.
2. 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.
3. V
TT
is not applied directly to the DIMM. 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
.
4. V
ID
is the magnitude of the difference between the input level on CK and the input level on .
