EVALUATION AND TEST
To evaluate and test the performance of the ADF4153, use the
following procedure:
1. Install the SDP-S software drivers and ADF4153-4-6-7
software. Connect the evaluation board to a PC using the
supplied USB cable. Follow the hardware driver installation
procedure that appears.
2. Connect the SDP-S connector to the EV-ADF4153SD1Z.
3. Connect a spectrum analyzer to Connector J2.
4. Run the ADF4153-4-6-7 software.
5. Select the SDP board and the ADF4153 device in the Select
Device and Connection tab of the software front panel
window.
6. In the software window, set the VCO center frequency
(Figure 19 shows a screenshot of the signal source analyzer
operating in phase noise mode, taken at a carrier frequency
of 1750 MHz). Set the proper PFD frequency to 25 MHz,
and program the reference frequency to equal 25 MHz.
The charge pump current should equal 2.5 mA. See
Figure 20 for the suggested setup.
7. Measure the output spectrum. Figure 19 shows a
1750 MHz output.
