Pin Description
Input Crystal connection. Connect to the external pullable crystal.
— Do connet to this pin.
Input Voltage input to VCXO. Zero to VDD signal which controls the
VCXO frequency.
Power Connect to ground.
Output VCXO CMOS level clock output matches the nominal frequency of
the crystal.
Power Connect to +3.3 V (0.01 µf decoupling capacitor recommended).
Input Output enable, OE=1 enables outputs, OE=0 disables REFOUT,
internal pull-up.
Input Crystal connection. Connect to a pullable 20 to 52 MHz crystal.
