, unless otherwise noted.)
Note 1:
Best-fit straight-line linearity method.
Note 2:
A typical application will AC couple the analog input to the DC bias level present at the analog inputs (typically 2.35V).
However, it is also possible to DC couple the analog input (using differential or single-ended drive) within this common-
mode input range (Figures 4 and 5).
Note 3:
PSRR is defined as the change in the mid-gain, full-scale range as a function of the variation in V
CC
supply voltage,
expressed in decibels.
Note 4:
The current in the V
CCO
supply is a strong function of the capacitive loading on the digital outputs. To minimize supply tran-
sients and achieve optimal dynamic performance, reduce the capacitive-loading effects by keeping line lengths on the dig-
ital outputs to a minimum.
Note 5:
Offset-correction compensation enabled, 0.22μF at compensation inputs (Figures 2 and 3).
Note 6:
t
PD
and t
SKEW
are measured from the 1.4V level of the output clock, to the 1.4V level of either the rising or falling edge of a
data bit. t
DCLK
is measured from the 50% level of the clock-overdrive signal on TNK+ to the 1.4V level of DCLK. The capac-
itive load on the outputs is 15pF.
