RELATED DOCUMENTS
Data sheets are available for both the AD911x and AD971x
products for product-specific details, including register defin-
itions. The DPG2 user guide is also available for assistance with
vector generation and loading.
GENERAL DESCRIPTION
This user guide describes the AD911x and AD971x evaluation
boards, which provide all of the support circuitry required to
operate the AD911x and AD971x in their various modes and
configurations. The application software used to interface with
the devices is also described.
The AD9114/AD9115/AD9116/AD9117 and AD9714/AD9715/
AD9716/AD9717 data sheets, available at www.analog.com,
should be consulted when using the evaluation board. The
AD971x/AD911x Rev. A evaluation board operates together
with the Data Pattern Generator 2 (DPG2) and the DAC
software suite, including the AD971x/AD911x update.
The CD-ROM provided with the evaluation board includes
the installation program for all necessary software. The install
program can also be downloaded. Both methods install the
DPGDownloader program for loading vectors as well as the
AD971x/AD911x update necessary for SPI communication.

These Clock DAC Output Single-Ended Quadrature Source Default Buffered Modulator currents are converted to voltages with loading resistors. By default, the output loads are provided by on-board resistors. R15, R16 R11, R38 Alternatively, on-chip resistors can be used.
