1)
V
REF
is expected to equal 70% of
V
for 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%
V
REF
(DC). Thus, from 70% of
V
DDQ
,
V
REF
is allowed ± 19mV for DC error and an additional ± 27mV for AC
noise.

1) The DC values define where the input slew rate requirements are imposed, and the input signal must not violate these levels in order to
maintain a valid level.
2) Input slew rate = 3 V/ns. If the input slew rate is less than 3 V/ns, input timing may be compromised. All slew rates are measured between
V
IL
(DC) and
V
IH
(DC).
3)
