2. Although DM is an input-only pin, the input capacitance of this pin must model the input capacitance of the DQ and DQS pins. This is
required to match input propagation times of DQ, DQS and DM in the system.

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 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
.
4. V
ID
is the magnitude of the difference between the input level on CK and the input level on CK.
5. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temperature and
voltage range, for device drain to source voltages for 0.25 volts to 1.0 volts. For a given output, it represents the maximum difference
between pullup and pulldown drivers due to process variation.
