LAYOUT EXAMPLE, EVALUATION BOARD, AND
SOFTWARE
The evaluation board and its accompanying software provide a
simple way to evaluate the AD9864. The block diagram in
which is designed to be flexible, allowing configuration for different applications.
The power supply distribution block provides filtered, adjust-
able voltages to the various supply pins of the AD9864. In the
IF input signal path, component pads are available to implement
different IF impedance matching networks. The LO and CLK
signals can be externally applied or internally derived from a
user-supplied VCO module interface daughter board. The refer-
ence for the on-chip LO and CLK synthesizers can be applied via
the external f
REF
input or an on-board crystal oscillator.
The evaluation board is designed to interface to a PC via a
National Instruments NI 6533 digital IO card. An XILINX FPGA
formats the data between the AD9864 and digital I/O card.

Evaluation Board Platform
Software developed using National Instruments’ LabVIEW
(and provided as Microsoft Windows executable programs) is
supplied for the configuration of the SPI port registers and
evaluation of the AD9864 output data. These programs have a
convenient graphical user interface that allows for easy access
to the various SPI port configuration registers and frequency
analysis of the output data.

ing an example layout, please refer to the EVAL-AD9874EB
