AD9785/AD9787/AD9788 EVALUATION BOARDS
The remainder of this data sheet describes the evaluation
boards for testing the AD9785, AD9787, and AD9788 devices.
OUTPUT CONFIGURATION
Each evaluation board contains an Analog Devices ADL5372
quadrature modulator. The AD9785/AD9787/AD9788 devices
and the ADL5372 provide an easy-to-interface DAC/modulator
combination that can be easily characterized on the evaluation
board.
Solderable jumpers can be configured to evaluate the single-
ended or differential outputs of the AD9785/AD9787/AD9788.
The factory default jumper configuration is as follows:
Jumpers JP2, JP3, JP4, and JP8 are unsoldered.
Jumpers JP14, JP15, JP16, and JP17 are soldered.
To evaluate the ADL5372 on the evaluation board, reverse the
jumper positions as follows:
Jumpers JP2, JP3, JP4, and JP8 are soldered.
Jumpers JP14, JP15, JP16, and JP17 are unsoldered.
Note that the ADL5372 also requires its own separate 5 V and
GND connection on the evaluation board.
