EVALUATION BOARD

The AD9281 evaluation board is shipped “ready to run.”

Power and signal generators should be connected as shown in

Figure 33 Then the user can observe the performance of the Q

channel. If the user wants to observe the I channel, then he

should install a jumper at JP22 Pins 1 and 2. If the user wants to

toggle between I and Q channels, then a CMOS level pulse train

should be applied to the “strobe” jack after appropriate jumper

connections.
