FEMTOCLOCKS™ CRYSTAL-TO-LVHSTL FREQUENCY SYNTHESIZER
PRELIMINARY
Schematic Example
Figure 4 shows an example of ICS8422002I-01 application
schematic. In this example, the device is operated at V_DD = 3.3V.
Both input options are shown. The device can either be driven
using a quartz crystal or a 3.3V LVCMOS signal. The C1= 22pF
and C2 = 22pF are recommended for frequency accuracy. For
different board layout, the C1 and C2 may be slightly adjusted for
optimizing frequency accuracy. The LVHSTL output driver
termination examples are shown in this schematic. The decoupling
capacitor should be located as close as possible to the power pin.
