Ground. DC power is provided to the device on these pins.
No Connection. (Do not connect to ground.)
Oscillator Ground. DC power is provided to the oscillator on these pins.
Oscillator Power Supply. DC power is provided to the oscillator on these pins.
2-Wire Slave Address Input. This pin is used to configure the slave address.
DC-TCXO Frequency Output
2-Wire Serial-Data Input/Output. SDA is the input/output pin for the 2-wire serial
interface. The SDA pin is open drain and requires an external pullup resistor.
Power Supply. DC power is provided to the device on these pins.
2-Wire Serial-Clock Input. SCL is used to synchronize data movement on the serial
interface. The SCL pin is open drain and requires an external pullup resistor.
