AD9060/PCB Evaluation Board Block Diagram

Onboard reconstruction of the digital data is provided through

the AD9712, a 12-bit monolithic DAC. The analog and recon-

structed waveforms can be summed on the board to allow the

user to observe the linearity of the AD9060 and the effects of the

quarter-point voltages. The digital data and an adjustable Data

Ready signal are available via a 37-pin edge connector.

AD9060/PCB EVALUATION BOARD

The AD9060/PCB Evaluation Board is available from the fac-

tory and is shown here in block diagram form. The board in-

cludes a reference circuit that allows the user to adjust both

references and the quarter-point voltages. The AD9617 is in-

cluded as the drive amplifier, and the user can configure the

gain from –1 to –15.
