Crystal or clock input. Connect to a 25 MHz crystal or single ended clock.
Connect to +3.3 V.
Connect to ground.
Connect to +2.5 V or +3.3 V. For CLKA outputs only.
Clock A output with weak pull-down resistor.
Clock A output with weak pull-down resistor.
Connect to ground.
Select pin 1.
Select pin 0.
Connect to ground.
Clock B output with weak pull-down resistor.
Connect to +2.5 V or 3.3 V. For clock output B only.
Connect to ground.
Output enable tri-states outputs and device is not shut down. This input
has internal pull-up resistor. OE = 1 enables outputs A and B and OE=0
disables outputs A and B. When disabled the pull-down resistor pulls the
outputs to GND.
Connect to +3.3 V.
Crystal connection. Leave unconnected for clock input.
