EVALUATION BOARD HARDWARE

OVERVIEW

The EV-ADF5355SD1Z requires the SPD-S platform which uses the EVAL-SDP-CS1Z. SDP-B is not recommended .

POWER SUPPLIES

The EV-ADF5355SD1Zis powered from dc power connectors 4 mm banana connectors . When feeding via banana connectors, V is a suitable feeding voltage. The power supply circuitry allows the user to use two or three separate LDOs to feed the ADF5355 using fewer LDOs increases the risk of spur contaminated dc feeds . Ensure the switch is in the correct position to power the board. Consult the board schematic in Figure 20, Figure 21, and Figure 22 to determine a suitable setting.

The charge pump and VCO supply pins are driven from a 5V ADM7150 high performance low noise regulator. The remaining supplies are powered from 3.3V ADM7150’s.

An LED, indicates when USB power is available, and another LED, indicates when the ADF5355 is powered on. Switch S1 is used to power the ADF5355 from the external dc connectors, and should be switched to the left.

In case the SDP processor causes spurs on the RF output signal, the user may remove this connector and measure the spurious.

RF OUTPUT

The EV-ADF5355SD1Z has one pair of SMA output connectors differential outputs RFoutA+/- . The device is quite sensitive to impedance unbalance. If only one port of a differential pair is used, terminate the other with a 50 Ω load. If only RFoutB is used, then it can be powered off, or if left on, both RFoutA pins should be terminated in 50 Ohms.

The RFoutB contains the high frequency GHz and is a single ended RF output.

LOOP FILTER

C60 = 22 nF, C59 = uF, C14 = 10 nF, C73 = 10 pF. R14 = 220 Ohms, R1 = 470 Ohms. Customers wishing for lowest rms phase noise should use C60 = nF, C59 = 33 nF, C14 = 390 pF, C73 = 10 pF.

REFERENCE SOURCE

The evaluation board contains a footprint for a MHz differential output TCXO from Vectron. If preferred, the user may supply either a single-ended or differential reference input to connectors REFINA and REFINB. Disconnect the power rail to the TCXO by removing resistor R12 first. To use a single ended REFIN, then connect a low noise MHz reference source to REFINB. To use a differential REFIN connect the differential signal to REFINA and REFINB. The differential REFIN can operate to 500 MHz input frequency. If the TCXO is removed, then an external REFIN must be used.
