AD9144 Evaluation Software
The AD9144 Evaluation Board software runs on the easy-to-use SPIPro graphical user interface (GUI).
It is included on the Evaluation Board CD. Registers on the AD9144 and AD9516 products are
programmed via a USB cable connecting the user’s PC to the AD9144-FMC-EBZ XP2 connector.
Software in the AD9144-FMC-EBZ PIC processor (XU1) provides the interface between the USB bus
and the SPI busses of the AD9144 and AD9516.
Hardware Setup
C5.0V to P5, GND to P6. A low phase noise high frequency clock source should be connected
to the SMA connector, J1. This is the DACCLK input. The spectrum analyzer should be connected to
the SMA connector, J4. A +1.0V power supply must be connected to the VTT probe point near SMA
connector J9, along with a GND connection to the GND probe point next to it. The evaluation board
connects to the DPG3 through the connectors P4. The PC should be connected to the EVB using the
mini-USB connector XP2 after installation of the Evaluation Board software. Figure 1 shows the block
diagram of the set-up.
