Notes:
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.
