5 The EVM Configuration

The ISO721EVM configuration has an SMA connector J3 set up as the input to pin 2, the IN pin of the ISO721 in Figure 3-1 and Figure 4-1. A 0-Ω input series resistor, R8, is located next to the J3 input connector, and a 50-Ω R5 from the input to ground is located on the bottom of the board.
