ADL5723 Data Sheet EVALUATION BOARD
The ADL5723-EVALZ comes with an ADL5723 chip. It supports
RESULTS
a single 5 V supply for ease of use. For 5 V operation, use the Figure 18 shows the expected results when testing the 3.3 V and 1.8 V test loops for evaluation purposes only. When ADL5723-EVALZ using the Rev. A version of the evaluation using a 3.3 V or 1.8 V supply, remove the R1 and R2 resistors board and its software. Note that future iterations of the software from the evaluation board. Figure 19 shows the ADL5723- may produce different results. See the ADL5723 product page EVALZ evaluation board lab bench setup. for the most recent software version.
INITIAL SETUP
Figure 18 shows the results of the differential output for an input To set up the ADL5723-EVALZ, take the following steps: of 10.1 GHz at −15 dBm. The hybrid and board loss have not 1. Power up the ADL5723-EVALZ with a 5 V dc supply. The been deembedded. supply current of the evaluation board is approximately

111 mA, which is a combination of the VCC1 (1.8 V) and
10 1 SWEEP = 301ms (1001pts)
the VCC2 (3.3 V) currents.
