Description
Crystal connection or clock input.
Connect to +3.3V or +5V.
Connect to ground.
Nothing is connected to this pin.
Clock output per Table above. Output frequency equals input frequency times multiplier.
Select 0 for output clock. Connect to GND or VDD or float.
Select 1 for output clock. Connect to GND or VDD or float.
Crystal connection. Leave unconnected for clock input.
Pin Descriptions
Key: I = Input, TI = Tri-Level Input, O = output, P = power supply connection
Clock Decoding Table (MHz)
0 = connect directly to ground, 1 = connect directly to VDD, M = leave unconnected (floating).
