DESCRIPTION
Power supply
Buffered output reference. 3.3V
Digital Ground.
Not connected.
Clock outputs - controlled by 3.3V VDD
Frequency select inputs, these inputs have internal pull-ups.
Input for tristate. If PD# = 0, then all outputs are tristated and
the device is in shutdown mode (VCO’s off, crystal oscillator
is off and all logic is reset) When PD# = 1, the device is in
normal operating mode. Has internal pull-up
Analog Ground
Not connected
