Description
CLKIN/CLKINB.
These pins are used as the main differential clock input
or as the XTAL input. Clock inputs to these pins must be
ac-coupled. A crystal should be directly connected to
I
Multi
pins 1,2 with the shortest traces possible. 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.
