CLKIN/CLKINB.
These pins are used as the main differential clock input or as the
XTAL input. See "3.2. Input Stage" on page 17, Figure 3 and
Figure 4, for connection details. Clock inputs to these pins must be
ac-coupled. Keep the traces from pins 1,2 to the crystal as short as
possible and keep other signals and radiating sources away from
the crystal.
When not in use, leave IN1 unconnected and IN2 connected to
GND.
