Test Mode Select (LVCMOS). JTAG signal that controls the state transitions of
the TAP controller. This pin is internally pulled up to V
then it should be left unconnected.
Oscillator Master Clock Input (LVCMOS). This input accepts a 20 MHz
reference from a clock oscillator (TCXO, OCXO). The stability and accuracy of
the clock at this input determines the free-run accuracy and the long term
holdover stability of the output clocks.
Oscillator Master Clock Output (LVCMOS). This pin must be left unconnected
when the osci pin is connected to a clock oscillator.
Internal Connection. Connect to ground.
Internal Connection. Leave unconnected.
No Connection. Leave unconnected.
