The clock input is supplied by way of a single-ended signal to an SMA connector, and transformer coupled
to produce a differential clock signal for the ADC32/34xx EVM. For the ADC32J/34Jxx EVM, the clock
input can be generated onboard using the LMK04828.
Power to the ADC3xxx EVM is typically supplied from a 5-V bench supply using the onboard barrel
connector and the provided cable, or from an appropriate 5-V, 3-A minimum power brick. All necessary
voltages for the ADC EVM are derived from the 5-V input connection.
