GENERAL DESCRIPTION 

The 

EV-ADF4355-2SD1Z

 evaluates the performance of the 

ADF4355-2

 frequency synthesizer with integrated VCO for 

phase-locked loops (PLLs). A photograph of the evaluation 
board is shown in Figure 1. The evaluation board contains the 

ADF4355-2

 frequency synthesizer with integrated VCO, a 

differential 122.88 MHz reference (TCXO), a loop filter, a USB 
interface, power supply connectors, and subminiature Version 
A (SMA) connectors. A USB cable is included to connect the 
board to a PC USB port.  

For easy programming of the synthesizer, download the 
Windows-based software from 

www.analog.com/ADF4355-2

This board requires an 

SDP-S

 (shown in Figure 1, but not 

supplied with the kit). The 

SDP-S

 allows software programming 

of the 

EV-ADF4355-2SD1Z 

device.
