Introduction
Figure 2. Simplified ADC34J4x EVM Block Diagram
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 on board using the LMK04828.
Power to the ADC3xxx EVM is typically supplied by a single 5-V connection by way of a 5-V power brick.
All necessary voltages for the ADC EVM are derived from the 5-V input connection.
