-Once the DPGDownloader software is installed, the hardware can be connected . A single 5V power supply powers the evaluation board. The power supply should be able to source up to 1A to cover all of the board’s operating conditions. A low jitter clock source (< 0.5psec RMS) should be used for the DACCLK. A sinusoidal clock output level of 0 to 4dBm is optimal. By default, the DAC outputs are connected to SMA connectors for evaluation. Both DAC outputs are available. Later in the document, the modifications for observing the modulator output and different clocking options will be shown.+Once the DPGDownloader software is installed, the hardware can be connected .

-There are 6 pin jumpers on the evaluation board corresponding to the 6 supplies on the board. They serve as ‘switches’ that determine if the LDOs on board or external supplies are used for each individual supply. They are shunted by default, which means on board LDOs  are used. When an external supply is necessary, pull off the shunt from the corresponding supply and connect the external supply to the SMA test points close to the jumper.+There are 6 pin jumpers on the evaluation board corresponding to the 6 supplies on the board.
