ADL5724 Data Sheet EVALUATION BOARD
The ADL5724-EVALZ comes with an ADL5724 chip. It supports
RESULTS
a single 5 V supply for ease of use. Note that, for 5 V operation, Figure 18 shows the expected results when testing the the 3.3 V and 1.8 V test loops are for evaluation purposes only. ADL5724-EVALZ using the Rev. A version of the evaluation When using a 3.3 V or 1.8 V supply, remove the R1 and R2 board and its software. Note that future iterations of the software resistors from the evaluation board. Figure 19 shows the may produce different results. See the ADL5724 product page ADL5724-EVALZ lab bench setup. for the most recent software version.
INITIAL SETUP
Figure 18 shows the results of differential output for an input of To set up the ADL5724-EVALZ, take the following steps: 12.7 GHz at −15 dBm. The hybrid and board loss were not 1. Power up the ADL5724-EVALZ with a 5 V dc supply. The deembedded. supply current of the evaluation board is approximately
