data is valid on the rising edge of the input clock. The
output data has an internal latency of 5.5 clock cycles.
Figure 6 also determines the relationship between the
input clock parameters and the valid output data.
Applications Information
Figure 7 depicts a typical application circuit containing a
single-ended to differential converter. The internal refer-
ence provides a V
DD
/2 output voltage for level shifting
purposes. The input is buffered and then split to a volt-
age follower and inverter. A low-pass filter, to suppress
some of the wideband noise associated with high-speed
op amps, follows the op amps. The user may select the
R
ISO
and C
IN
values to optimize the filter performance, to
suit a particular application. For the application in Figure
7, a R
ISO
of 50
is placed before the capacitive load to
prevent ringing and oscillation. The 22pF C
IN
capacitor
acts as a small bypassing capacitor.
