Required Hardware

ML605/KC705/VC707 board (use the corresponding design file).

AD9739A-FMC-EBZ board

Spectrum Analyzer

Required Software

Xilinx ISE (Programmer (IMPACT) is sufficient for the demo and is available on Webpack).
Use the latest version or the one used in the reference design.

A UART terminal (Tera Term/Hyperterminal), Baud rate 57600.

Bit file

Download the gzip file and extract the sw/cf_ad9739a_mb.bit file.

Running Demo (SDK) Program

 for details. 

To begin, connect the AD9739A-FMC-EBZ board to the FMC-LPC connector of ML605 board (see 

image below). If using KC705 use FMC-LPC, if using VC707 use FMC1-HPC. Connect power and 
two USB cables from the PC to the JTAG and UART USB connectors on the edge of the ML605. A 

spectrum  analyzer  should  be  connected  to  the  output  SMA  jack  (OUT/J1).  This  quick  start 
program uses a 2.5GHz DAC clock and generates a 300MHz tone. Adjust your spectrum analyzer 

accordingly. On the AD9739A-FMC board, ensure that the SPI source jumper (SPI SRC/P2) is set
