3 Digital Interface

The AMC1333EVM digital input/output is a simple three-terminal screw connector located at J4. J4.2 is the output data from the modulator installed in location U1. As shown in Figure 3-1, pin 7 of U1 is the modulator clock output. The clock output can be monitored at J4.3 relative to J4.1. Figure 3-1 shows the digital I/O circuitry for the AMC1333EVM. Table 3-1 lists the digital output signals relative to J4.
