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 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 CLK and the input level on CLK .
4. 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 from 0.25 V to 1.0 V. For a given output, it represents
the maximum difference between pullup and pulldown drivers due to process variation. The full variation in the ratio of the
maximum to minimum pullup and pulldown current will not exceed 1.7 for device drain to source voltages from 0.1 to 1.0.
5. V
OH
= 1.95V, V
OL
=0.35V.
6. V
OH
= 1.9V, V
OL
=0.4V.
7. The values of I
OH
(DC) is based on V
DDQ
= 2.3V and V
TT
= 1.19V.
The values of I
OL
(DC) is based on V
DDQ
= 2.3V and V
TT
= 1.11V.
