EVALUATION BOARD HARDWARE
The evaluation board requires an SDP-S motherboard to
program the device. The SDP-S board is not included and must
be purchased separately. The EV-ADF5904SD2Z schematics are
shown in Figure 5 to Figure 9. The top layer and assembly layout
are shown in Figure 10.
POWER SUPPLIES
The evaluation board is powered via one external supply, 5 V
connected as described in the Quick Start Guide section.
INPUT SIGNALS
The LO input pin and the Rx input pins on the ADF5904
contain a dc bias voltage; the inputs must be ac-coupled to the
evaluation board.
