GPO = General purpose output
Supply Voltage.
Analog PLL power supply. Connect to 3.3 V.
No Connect/Crystal oscillator output.
If this device is to be used as the clock master in a multi-channel design, this pin
should be connect to the XTAL1 pin of a clock slave device. (Otherwise, this pin
should be left unconnected.)
