2.2 Digital Input and Output

The digital CLKIN input for the AMC33xxEVM is accessible on the three-wire screw terminal at J3 on pin 3. The CLKIN input should be supplied with a 5–21 MHz square wave which alternates between 0 V and VDD.

The digital output from the AMC33xxEVM board is a bitstream with a ones density proportional to the differential input voltage. Figure 2-2 illustrates that the DOUT output is available at pin 1 of J3 .
